I, have had this problem for a while, just never complained because it worked fine with my gtx 560. Now, Its starting to become a nuisance to me. I'm bottle necking like crazy today, when I installed my xfx 7950. I've tried everything. Pulling out the battery to the motherboard and putting it back in. Speaking about that, My motherboard is the gigabyte 78lmt-s2p. Which, I do not understand it is an AM3+ board Anyy suggestions?
