Wheat, to prevent bottlenecks in the hardware, you're gonna want an Nvidia card, one like papa's would work perfectly, intel and nvidia are built to work best together, same with amd and ati.
I personally run an amd build, but unfortunately do not have benchmarks at the moment, mobo is getting repaired lol

Either of these would work well, only difference between the 2 is vram, one has 2gb, the other has 1gb
the FTW edition 750 TIs are nearly identical to a 770
