Have an ASUS P6T looks like it is built specifically for the i7-900 series, and it seems to this layperson that the specifications in this family of CPUs don't vary enough to create compatibility issues with current top end graphic and audio cards so I'm hoping that this choice can be made before learning what brain is currently soldered to my motherboard. The other goodies he gave me are:

1 TB SATA hard drive: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136533&Tpk=wd1001fals&IsVirtualParent=1

and

750 GB SATA hard drive: http://www.newegg.com/Product/Product.aspx?Item=N82E16822145166

Ultimately I'm hoping to dual boot in linux and windows 7 (I don't want to touch windows 8 with a 10 foot stick). Linux is the ideal OS for the computations I hope to run. Some of my scientific computation colleagues say that with a quad core the machine should be strong enough to pull basic calculations in less than a week typically, which should be enough room for me to start stretching my wings before sending more complex computations off to a cluster run by the NSF which I just found out I have free access to as a fellow.

I'm currently looking at the Nvidia GeForce GTX690 (http://www.tomshardware.com/reviews/geforce-gtx-690-benchmark,3193.html). I do want to do a bit of gaming, and a fair bit of image processing, and this seems like it would exceed my requirements without necessitating the use of multiple GPUs (that is, except for the two GPUs they squished into the 690 itself!).

In terms of sound card I'm not sure which direction to go. I'm currently using an external sound card/interface that talks to the PC via USB and it's adequate, but I persistently have latency issues that make it prohibitively difficult to record most of my faster stuff. It seems like with external interfaces a latency of about 1 millisecond is about standard, and unfortunately this is much too much for my purposes. An on board card seems to be capable of offering less latency, but it's not clear to me what is the best way to manage this issue in terms of hardware.

Any suggestions on choice of sound and video cards? I also need to decide on a power supply and monitor. I have enough monitors lying around that I could hook up three if necessary (necessary might be a strong word here), but it would be nice to have one 30" display that can take advantage of the GTX690's juice. Suggestions are also welcome on those fronts.

In terms of dual booting in linux and windows 7, what issues might this cause on a system level? My buddy dual booted his monster machine with XP and windows 7 and had all kinds of stability issues because of it and I would very much like to avoid that, especially because during computations, all four cores will be chugging along at capacity for possibly multiple weeks straight and it really needs to be stable as a rock to support that kind of consistent load.

Finally, that video card uses an axial cooling fan, which it seems has a reputation for dumping all of it's heat directly into the tower rather than out of it. I've got a pretty robust fan on the CPU, but for such heavy computations and/or high graphics load gaming heat will be a definite issue. Any suggestions on effective case design and component arrangement to minimize this issue? If I go with the GTX690 I don't want to mess with multiple video cards and crossfire, so at least there will only be three massive heat sources to consider (CPU, GPU, and PSU I believe unless I'm missing something).

Thank you

If you are running an Asus P6T motherboard even the bottom end i7 CPU(unlocked) can get to very decent clock speeds, very easily. This was a very popular core build about 4 years ago and remains very relevant today as I have one =) There is no need to specifically identify your CPU any further, for now.

That RAM upgrade would work very nice.

Creative has a tool to utilize ASIO drivers in the X-Fi series of sound cards: http://support.creative.com/kb/ShowArticle.aspx?sid=88833

M-Audio also has some options. You should pick which one suits your needs based on your input/output requirements from there.

There are coolers you can mount right under-neath your video card to port its exhaust out the back of the case. I would use a card...
This would be a fun and juicy build. Wish I could be a part of it.

Don't go cheap on the power supply.
Dual boot system should not cause any stability problems.
A sound card that uses an ASIO driver should give you lower latency.
Get a case that can handle good air flow.
 
This thread won't get much traction unless you get a little more specific in what you want help with. I gather you have a motherboard with an i7 CPU(unknown model) and basically nothing else....

If you could offer a budget you are working with, maybe some people will start submitting some specific part recommendations.

Thank you skit75. I appreciate your response. My grandpa set me up with an ASUS P6T (http://www.asus.com/Motherboards/P6T/) and the items I listed earlier. I can't tell what processor it has since he's already installed it and the dedicated fan, but I'm pretty sure it's one of the i7-900 series, but I don't know which. I'm guessing the mid grade i7-950 (http://www.newegg.com/Product/Product.aspx?Item=N82E16819115211), but I don't want to remove the fan and heat sink to check it out.

Is there any reason to do this before building the tower and looking at the CPU in BIOS?

Any specific suggestions on choice of sound and video cards? (Primary use: Scientific Computations - Physics)

Any thoughts on the Nvidia GeForce GTX690 (http://www.tomshardware.com/reviews/geforce-gtx-690-ben...)? Do you have any suggestions for a diff card?

A recent development worth noting is my computation guru suggested I go with this memory pack: http://www.amazon.com/Corsair-Vengeance-Desktop-Memory-CMZ24GX3M6A1600C9/dp/B004UPTEH6/ref=pd_cp_e_3
I think the one that's in there now is a Corsair XMS3 version 2.3. There are six 2 GB memory cards of the model installed. What thoughts do you have on this memory upgrade?

Most of the components on this computer build were given to me by my grandpa - I would say I have 2K to work with.

What application will you be using for your modeling/rendering/number crunching? It is best to check the application's hardware compatibility list before making your GPU purchase.
