Motherboard and GPU help

the MB is a GA-B75M-D3H which has PCI 3.0... that said pci 2.0 x16 won't bottleneck any gpu out there anyway... it will be another generation or two before a gpu comes along that will be bottlenecked by pci 2.0 x16.

I wouldn't buy that pc though. $700 for that POS is far too much.
