I have a Gigabyte GA-P67A-UD3R motherboard with 2 PCI Express x16 slots the second one running at x4 (PCIEX4). It is not PCIE 3.0 it is only PCIE 2.0 with my cpu!
Would a 7770 saturate the PCIEX4 and would I notice a drop in frame rates if I installed that card there and decide to buy a AMD 7970 later if some fantastic new game comes out next year?
How to disable the 7770 while using the 7970 also? Why would I buy a cpu with integrated graphics in the future if the 7770 is better?? Also what motherboard/cpu to buy for these cards. Does a 7970 saturate a x8 slot on PCIE 2.0?
