I plan to buy a new machine for running my algorithm implemented in GPU under CUDA. I currently have a GTX 460 graphics card, and may get a GTX 590 a few months later.

I am not sure which CPU, mainboard, memory, case, power, etc. I should use, so as to make the machine run well.

Could you give me some advice?

Here are some advices based on my experience (I've tested several configurations for our university HPC center):

There is no difference which CPU to use (Intel or AMD), while it have at least (N + 1) cores, where N is numbers of GPUs you have.

Memory -- not less than your GPUs have.

Motherboard: must have PCI-Express 2.0 x16 slot for each card. Bus bandwidth is often limiting factor. No SLI needed.

Case and power --- just general considerarions (for reference, typical GPU consumes ~200W).

Of course, all common rules apply, I've mentioned only GPU-specific ones.
