Exactly what im thinking, has to be drivers or software problem in my oppinion, although i think a fresh windows re-install should fix things up......
So apperntly it wasnt my GPU or anything on the video side at all. Basically my mouse was causing the lag as it would only drop fps when i would move my mouse. Most of the games I play require a mouse so I didnt notice right away but I moved my mouse down to 125hz and its fixed everything. Still dont know WHY its all wierd at 1000hz but whatever, I fixed it so Im happy.
