Hi everyone
I've been searching the forum for an answer about it and couldn't find a real one..
So this is my concern , i have a ASUS Sabertooth 990FX 2.0R witch has PCIe 2.0 slots only, My GPU is a PCIe 3.0 - i know they work together BUT is my mobo PCIe 2.0 slot sort of "bottlenecking" my PCIe 3.0 GPU in any noticeable way? (maybe in OC or Crossfire?)

Thx very very much for any answer!

Solution
As long as it is an x16 lane there is no difference, if you get a card that CAN fill the lane then there would be, but those are cards like the titan and 7990.

Thx, so there is no difference in matter of graphics/games while OC or using crossfire as well ? even if there is a difference of like X2 more bandwidth in the PCIe 3.0 ?
