Here's my problem, my 2.0 pcie slot is kind of trashed, so i get crashes sometimes when using it, so i usually use the other slot which is 1.1, i've had no problems with any game except GW when using 1.1, however in GW fps drops by 50% or more on 1.1, which is weird since the bandwidth difference should not matter all that much especially in 1080p.
