2x GTX 670 running on PCI 2.0 x8 - Will PCI 3.0 at x8 or x16 improve performance?
Feb 24, 2014, 5:28 PM
I have an Asus lower end motherboard. I'm running two GTX 670 on PCI 2.0 x8 slots. Will running them on a motherboard that has PCI 3.0 with x8 or x16 slots improve performance? Thanks.

there will hardly be any noticeable perform rise(say about 0-2%)

Nope, well, not really, the performance will not be very noticeable if at all. GPU's don't really use enough bandwidth to max out a PCIE 2.0 slot.
Just keep your current motherboard for the time being.
