Recommended System Specs

I've been contacted about building a computer for someone but the system requirements page doesn't really tell you anything. All it says is SSE2 support which i believe everything has now, will look later. But does it benefit from nVidia's cuda cores in their Quadro cards vs. AMD firepro workstation cards (nvidia tends to work better with some things like this). And does it benefit from an i7's hyperthreading or can it only use 4 threads? Really the specs page is just terrible to be honest

Can someone post links to decent computers for this, maybe a cheap, average, and great computer? Just need to see what parts would be best so i can get a price quote or if those are cheaper i can just tell him that
