I'm seriously in the market to buy a new desktop PC.

I'm running three 19" Samsung screens and NT 7. Cable modem. WIN XP

Tell me what specs this needs and the best place to buy it.

Appreciate your feedback.

I would personally look at a desktop with at least a quad core processor. You don't need anything expensive. I have a Dell Inspiron 530 with a Q8300 and 8GB memory, Vista 64bit. I've had no problems with NT 7 and it runs very fast. I found it on eBay (refurbished) when they were giving discounts, but also dealnews.com sometimes have good sales on desktops.

I've always thought of 2D graphics as being fast on any modern day card. I haven't read through this article yet but you might want to take a look.

I have built 4 computers in the last 18 months, all with Nvidia 9500 GT based cards. If you are building a computer for trading only, fancy graphics cards are not necessary, as you are only doing simple 2D graphics. You also don't need a ton of memory on the graphics card, but most of the cards are 512M/1G at this point.

Most cards can handle two monitors, but be sure you look for an adapter that has two dual DVI outputs, so you can connect two large monitors in the future.

Just go to NewEgg, and search on "9500 gt". There are a bunch of brands, that are all repackaged versions of the Nvidia design. I have used the Zotec brand, but it is not always in stock. There is a passive version of the Zotec, but the heat sink is pretty big if you are putting more than one in a box. Other kinds of cards work also, this is just what I have been using.

Depending on your motherboard, you can put up to 4 of these in a computer and power 8 monitors. We have built 2 & 3 adapter machines at this point and have had very good luck.

Zoe,

It seems you're building this desktop yourself ? If NO, what brand is it ? Is it going to be dedicated to run NT or you're using for other apps ?

Yes, it's custom built and dedicated for trading, strategy building and testing.

Zoe,

Although, I'm not an advocate for a custom-built system for trading activities, an Intel-based system should add more quality and performance to the desktop system. Also, a 128GB or 256GB solid-state drive should suffice (instead of the 1 TB HDD); the SSD don't have moving components; they are faster, more reliable, and they consume very very little power.

Actually, the AMD gives more bang for the buck. I've been using an AMD processor and motherboard with my current 5 year old box and had no issues. One pays a premium for the Intel brand, all other things equal.

SS drives are too expensive considering the alternative. They are where flat screen tvs were 10 years ago in terms of price performance. I use a RAID system now and don't want to give that up. Also, I've never had a hard drive fail (knock on wood).

If this computer were purchased from a Dell, HP or other branded manufacturer, it would be much more expensive than the $1300 I'm paying which includes the cost to built and test it.

The prices are pretty attractive; the 955 will sell for $245 (and it already has been) and the 945 will go for $225. That pits the 955 against Intel’s Core 2 Duo Q9550 ($266) and the Core i7-920 ($284), the latter having a much higher motherboard cost of course.

Unless you’re running applications that are very well optimized for Intel’s architectures, the Phenom II X4 955 is faster than the Core 2 Quad Q9550. Compared to the Core i7-920, it loses hands down although the chip does come close in some games.

No. I think this is fast enough for the trading apps and I don't want the additional heat generation either. My experience with overclocked trading computers didn't result in much of a difference in realworld use.

I'm thinking about replacing the video card since it's really for gaming and it's also sold out at most places I shop.

Feel free to recommend an ATI card to support three 21 inch monitors.

You got me curious Zoe and I'm trying to learn more of this stuff and found this for 3 monitors but its a pricey gamers card:

Newegg.com - SAPPHIRE 100282SR Radeon HD 5850 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card w/ATI Eyefinity - Desktop Graphics / Video Cards

For running multiple monitors, two video cards would work.. and you'd have an extra output for a 4th monitor if you wanted to add one later.

Since ninjatrader makes absolutely no use of 3d acceleration and is not likely to any time soon, you'd be just as well off with a couple of entry level cards at $60 to $120 each as you would be with a more expensive card.

I think the processor is the only thing that will give you a noticeable performance boost. The video card and hard drive speed will probably not matter at all. RAM speed does not matter at all either in my experience, although you want plenty of it.

Motherboard stability is also worth paying more for, which is an argument for spending the extra dollars for a good motherboard. You might want a motherboard that is designed for heavy useage such as for servers or serious workstations.

I would stay away from RAID 0. The performance boost is negligable and your chance of hard drive failure increases exponentially. You will be just as happy with a simple cheap hard drive as you would be with anything more expensive.

SSD drives are not worth it either. I have one and the performance boost is not noticeable at all for trading.

Yeah, that's a step up from what I didn't want. It's a gaming powerhouse card and besides, you have to get a display port cable to hook in the third monitor which adds about $75.

I have been using two Nvidia GT9500 cards in the current box and they are really adequaite except for the fan noise. The new box has to run super quiet, that's one of my requirements, so I'll probably go with two cards with passive cooling.

My current box has RAID and although your probably right, I'm going to stick with it.

Im going to back up the stuff with Acronis software.

Asus recommends two EAH4350Silent cards. Nvidia recommends two QuadroNVS290 cards.

looking for passive cooling, thats absolute worth it if you build machine for trading and dont need gamer+3d- power.

i run fanless matrox cards since years + can recommend this.
but also there are cheaper passive cooled cards out there.

Matrox was my first choice. They have legendary 2D enterprise cards, but the cost for one that runs 3 screens is out of my budget, unfortunately.

Need to replace my system which is about 4 years old. Do not want to build anything but just make a reasonable purchase.

Required: Reliable workstation with reasonably strong processor, Windows 7 64-bit, to connect up to 4 monitors (2560 x 1600), 3 year-onsite-service

Found:

- Dell Precision T3500
- HP z400
- Lenovo S20

All come with a Intel X58 express Chipset, at least a Xeon W3530 processor and can use two nVidia NVS 295 graphics adapters to connect the 4 monitors. Can be easily ordered online, no custom-built features required. The HP and Lenovo workstation come without the graphics adapters, so I need to get them separately to put them into the machines.

All machines can be upgraded to connect 8 monitors (HP officially only supports 6) by using NVidia NVS 450 cards, probably will never need this. Information overload confuses and does not help.


Question

(1) Have not been able to find appropriate documentation on the noise levels generated by these systems - referring to fan noise under moderate processor load.

(2) Does anybody have an idea about the support levels for Dell, HP and Lenovo?


My current system is a Dell workstation. The only thing that I do not like is the noise.

I seem to be in a similar situation as Fat Tails...

But I want to upgrade my video card from having dual capabilities to three monitor viewing.

I have an old Dell computer with a 305 watt power supply. The video card I purchased is a ATI Radeon 5450 (Display: up to 3 monitors) The video card requires a minimum of 350 watts power supply.

I purchased a New Dell 375 watt power supply from a vendor, who claimed it was new. I just received it yesterday and opened it up today only to see that the wires are all dusty and the fan is dusty as well...but I figured I'll go and install and see what happens. Golly geez it boots up...note: my CPU temperature with the old power supply hovers around 50c, but with this new power supply my cpu temp shot up to 68c with in 5 minutes...thus replacing the power supply back to the original.

Question:
Can I run the video card with just a 305w power supply??? It uses a passive heat sink and it won't be used for games or any 3d graphics....it'll be used just for charts on 3 monitors.

I don't want to hunt down another power supply and wait for its delivery...brr

Fat Tails I have a T3500 and it is very quiet. The UPS and the eSATA RAID I have connected to it make more noise.

Dual NVS295s, Xeon 3520. Its about a year old. Never any probs.

I really don't know if graphic card will make your trading better. I think if you focus on trading computer, just make sure it got good CPU power, enough ram, enough harddisk, good enough graphic card to render chart (Even built in one will do an excellent job thesedays).

I am sure that a graphic card will make my trading better, because without one my monitors will remain dark. All suited workstations can be equipped with 2 low cost 2D graphics adapters and you can then connect 4 monitors, if need upgrade to 6 or 8. You cannot use a graphic chip on the motherboard to connect 4 monitors and the workstations do not have one.

I agree that CPU power is most important, as this is the bottleneck of my current equipment. Will take one of the better Xeon Quadcores and the cheapest graphics adapters which are certified for the workstations For all of them (Dell, HP or Lenovo) this seems to be the nVidia NVS 295 adapter. My current system runs on two NVS 285, and they do fine.

I have build many computers over the years for traders, and non-traders, and the last several I have build both Intel based and AMD based, I have been very pleased with the AMD based ones, 1 due to cost, and 2 due to performance, the AMD black edition is a 6 core CPU and can be over-clocked if you want to do so...

I agree with the Solid State drives, as it really speeds things up.

Having enough RAM in your system is a MUST, when you system starts paging (using your hard drive as RAM) things start slowing down...

Acronis is what I use to backup my computers, and storage to a NAS, using RAID 5.

Graphics cards is a interesting topic, I have used several of the ones listed in this forum, and like the ones listed, I have been sticking lately to ATI 2460 PCIE cards, they have been very good cards. As stated earlier in this thread, charting is a 2D function, price goes UP/DOWN/or sideways, so all the fancy 3D cards, that can do this that and the other, are just over-kill... Unless of course you are doing 3D charting....... or using your computer to play games on...

Have you worked on the Radeon 5450 1gb with display port? If so, please let me know. I'm waiting for my power supply, 500w. I also found out that my socket 775 will support an Intel Q6700 quad core. So I would be able to upgrade my CPU.... If not, it's cool...no worries.

That graphics card is for gaming...
Its a PCI Express X16 card, which is good, but in my humble I shy away from gaming cards and just stick to cards for 2D functions.

But if you are happy with it, and you got a good deal on it, then I am sure it will be fine for you.

Well, all I have on my mother board are 2 pci slots and 1 pcie slot. I can't use 2 pcie video cards, so I can only use one video card and this is the only video card that will support 3 monitors.

Having said that, I would like to know if there's difference between using (1.vga to vga, 2.diplay port to vga, and 3.dvi to vga) or (1.vga to dvi, 2.diplay port to dvi, and 3.dvi to dvi)? ie. video card to monitor.

thx

yea that use what you can use as far as your motherboard goes...

VGA - VGA connector - Wikipedia, the free encyclopedia

VGA on your graphics card to VGA on your display is fine, and will work. Display port is just a way to "cram" extra video ports onto a single card. Mostly with a dual video card, they will put 2 VGA outputs on a single card, but above that, and they use a display port and then typically a cable of some sort, to connect the VGA into.
DVA to VGA you have to be careful with this, as if you monitors are VGA and you are trying to send DVI digital signal to a VGA it wont work. If the graphics card supports VGA, and it has DVI output, perhaps using a converter than you are ok.

But before you buy, check the manufacture, and look to verify they support what monitors you are going to use.

The other differences, are just what the card offers on the output: if the card can do VGA then it can do VGA card out to VGA monitor in. If VGA/DVI out, then it can do either or, mostly they do this with a simple VGA to DVI adapter.

hopefully that answered your question if I understood it correctly/

VGA = analog signal transfer - OK for old screens with only VGA input

DVI = digital signal transfer -- best for new screens wich have this as input-option

HDMI = same as DVI (digital ) but HDMI has in addition a sound-transfer (for movies / TV iE)

From a practical point of view, I assume that you want to connect 3 or 4 flatscreens.

-> Flatscreen prices have come down, so you might want to connect a few 30'' monitors and not a whole pack of 19"" screens

-> For those 30'' screens you would like to use a resolution of 2560 x 1600 pixels, you can reduce that resolution once you are older than 70 years.

Starting from here:

-> VGA is nonsense, converting a digital signal from your graphics adapter to an analog signal for transfer and then letting the monitor converting this back to digital does not make sense and reduces the quality.

-> Now, if you compare DisplayPort, DVI and HDMI, the main differences are the data transfer rates. For a resolution of 2560 x 1600 pixels, you would need

DVI: 6 lines -> 7.92 Gbyte/sec
HDMI: 3 lines -> 8.16 GByte/sec
DisplayPort: 2 lines -> 8.64 GByte/sec

However, as far as I know, there are only few 2560 x 1600 monitors that support HDMI, so HDMI will not be a choice that needs to be considered

-> To connect a 2560 X 1600 monitor via DVI you need a dual-link connection between graphics adapter and monitor. This requires that the graphics adapter supports dual-link. So to connect two monitors via DVI with a resolution of 2560 x 1600 you would need a graphics adapter with double dual-link capabilities. This is a question of the chipset used for the graphics adapter.

-> DisplayPort supports even higher resolutions. Also there is no problem to connect 30'' monitors with a 2560 x 1600 resolution. I come back to what I have written before:

Solution

Just buy two cheap nVidia NVS 295 (2D) graphics adapters. They sell about € 100,- per piece and come with 2 DisplayPorts each. Allows you to connect four 30'' monitors with 2560 x 1600 resolution. It is a passive card, so it will produce no noise.

If you only have one PCIe slot, you can use a graphics adapter, which has 4 DisplayPorts and will allow you to connect four 30'' monitors with a 2560 x 1600 resolution. For example you could select the nVidia NVS 450 card. This will cost you about twice as much as two of the smaller graphics adapters. NVS 450 is also a quiet, passive adapter.

Thanks for the replies, but I have to apologize for not being clear in my question. I assumed that when c12345 stated that he had working knowledge of the video card, I assumed that he would have understood my question.

So I will try to be as clear as I can.

My goal is to have “consistency of resolution” across the 3 monitors. If I have to sacrifice resolution to get consistency…so be it.

This is what I have in possession:

-1 radeon 5450 video card (see attachment)
-3 monitors 22” each with resolution 1680x1050
-1 pcie slot on mother board
- All adapters
VGA to DVI adapter
DVI to VGA adapter
Displayport to DVI adapter
Displayport to VGA adapter

Now there are basically two conditions.

Condition A. (connections)

From video card VGA port to VGA port of Monitor 1
From video card Displayport to Displayport VGA adapter to VGA port of Monitor 2
From video card DVI port to DVI/VGA adapter to VGA port of Monitor 3


Condition B. (connections)

From video card VGA port to VGA/DVI adapter to DVI port of Monitor 1
From video card Displayport to Displayport DVI adapter to DVI port of Monitor 2
From video card DVI port to DVI port of Monitor 3


So, which condition will give me consistency in terms of resolution across all 3 monitors?

  • Condition A
  • Condition B
  • Both A and B
  • Neither A or B

If you don’t have the answer, it’s cool….no worries…since I can do both conditions I’ll just use the trial and error methodology….thx

Hi,

If by “consistency of resolution” you mean all 3 monitors with the same resolution, you should be fine, all conections will do the full resolution of your monitors.

I would keep it simple and use only the necessary adapters so, assuming you have both VGA and DVI on the monitors:

VGA on card to VGA on monitor 1
DVI on card to DVI on monitor 2
Displayport on card to DVI adapter to DVI on monitor 3

The only thing here can be a slight less image quality from the VGA connection wich you may or may not notice but the resolution should be the same and set to the full resolution of the monitors.

Hope this helps.

Yes, indeed. You were spot on! You were correct about the VGA, very subtle difference, couldn't really tell unless you were really really looking. Thanks again.
