While playing Skyrim, my crossfire setup jumps around. It's like very weird stuttering. I'm not sure why it's doing this. Anyway, I've got one stick of 8GB memory that's 1600 Mhz. I've also got a motherboard that has a 16x PCI-E slot and a 4x PCI-E slot. COuld one of these the problem of my game jumping around so much? Any help will be much appreciated.
