Solved 2x GTX 670 running on PCI 2.0 x8 - Will PCI 3.0 at x8 or x16 improve performance? Tags: Asus PCI Motherboards Graphics Gtx Performance Last response: February 25, 2014 3:49 AM in Graphics & Displays Share davidst95 February 24, 2014 5:28:18 PM Hi, 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.

Reply to brarboy Share RefinedComputing February 25, 2014 3:49:32 AM 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.
