As for the tower, here's what I built with some help:)

Intel Z68 Core i5/i7 Configurator
1 x Case ( NZXT Gamma Gaming Case - Black )

Let me know what you guys think.

$1,345 total Beats $2,400!:)

I had reviewed your config. Looks like you made a few different choices (e.g. Windows' edition and 1 more data hard disk). It looks good. Have fun!


RE: I'm sure I can get my computer guy to add the four 295 cards pretty reasonably. Or, is this something I can do myself?

Do you know how to use a small screw driver and hook up cables? If not, pay the guy $100/hour to do it.

Seriously though... the challenge would be to use the driver software to set things up.

Remember to use only 1 dual card first at the beginning. Once you have configured correctly for the first and second monitors, then shut down the computer and add one the second video card (to hook up and test the third and forth monitors), and so on.

I'm needing 1000 watts to run eight 22" monitors with the above setup I was helped with putting together? It sounds like it unless I plugged in the wrong information.:( :p from the link.

Btw, I can go with this system above rig, 8 21.5" Asus 1920x1080 thin bezel monitors @ $129 each, plus the couple hundred I have in the Ergotron quad monitor stands I bought extra of at a discount, and 4 295 cards = $2940 :) for everything besides the power backup. Any ideas on that?

Again, as explained above... you don't use the computer's power supply to provide power to the 8 external monitors. Don't use the power calculator that way. It's the video card that is in question. Not the monitor.

For 4 NVS 295 cards, you are plenty fine with 800W or 1000W power supply.

Don't put a Ferrari engine on a Pinto. :D

Have no idea why the bios screen became inaccessible in the first place, but all is fixed now.

I had that happened to me a couple of times. Before I realized...

On some of the monitors themselves, I had accidentally hit the "SOURCE" button (to select between analog (VGA) and digital (DVI) input) and the monitor is taking video signals from the port that is not connected. (So nothing displayed on the screen.) I didn't realize it. It's easy to do on some monitors because the two buttons are next to each other. Of course the Windows login logo is also defaulted to the "primary" monitor. I tried to seek for the BIOS and couldn't see it. :)

Took me some swapping cables and monitors to figure that out. :)

RE: Power Supply

In your list, you had already configured a 1000W power supply. (You bought the 800W but they threw in a free upgrade to 1000W. So you will have 1000W.) This is probably about as high as one can have. On my older HP box, it only used a 350W and had worked fine for 3 PCI/PCIeX16 cards for a few years.

Also: you don't power the 8 monitors with this power supply. Each monitor has its own power supply and each needs to be plugged in to the 110V circuit (the wall) separately. How many monitors you use is irrelevant to the power supply rating used for your computer. The only thing that affects it is the graphics card model and how many of them. Since you will be using the low-end dual cards, their power requirements are almost insignificant. You can get yours going at 500W - 600W. 800W if you want to be more comfortable. 1000W is absolutely worry free.

Yes when I calculated my build it was something like 400 watts total with one vid card. I added 200 for two additional cards and have room to go with the 850 w.
 
LEAPup that build looks really great but what about all the video cards ?
It looks like you selected two cards ( not sure if both AMD Radeon HD 6450 ) supporting 4 monitors. Are you adding another two cards for 8 monitors ?

Also you can save on the additional audio and lan cards as the board is already equipped unless you are looking for something different in audio

LEAPup bought a higher priced motherboard to get 4 PCIe X16 slots. Should make the money worth and use 4 dual cards. :)

I am an advocate in using 4 x dual head cards (inexpensive) than 2 x quad cards (expensive). 2 supporting reasons:

1. Lower cost in replacement if one goes out
2. Smaller impact during the down cycle of one card (2 monitors out instead of 4 monitors out)

The NVS 295 will work fine.

Me I use 4 of these simple EVGA 8400 GS dual head cards. (Now $19.99 as new... I bought mine around $39.95). They work fine.

I see no reference to dual head at the link. Do\can you run one VGA and one DVI?

This motherboard should take 4 small PCIx X16 video cards fine. But it can't take 4 of the video cards like what you use though because yours have big cooling fans that take up the space of the next slot. :)

Yes... those cards look perfect for fitting in the board. They should fit nicely.
That is a great MB and will do the job well.
That is a problem with some of thses video cards they are so big they cover other slots and leave them unusable.

RE: SSD

You will experience a boost in performance in the following tasks/events:

1. Computer boot up
2. Starting of your application software
3. Reading/writing data to the disk by your trading app

For #1 and #2, you typically only do once a day. Not a good justification for getting a SSD.

For #3: if your trading apps constantly doing data read/write from the disk (not the network), then SSD should help you. If not a whole lot, then SSD can be skipped.

Greatly appreciate the advice! Btw, since it's close to my B-day (D-day:( ), will you skip sending me a bill for this?:) :D
