Wow what is your clock at and is your refresh rate the same as it is monitor. try ruuning cool bits ad truning down your 3d clock rate not the 2d one. It should be running at 350 if its higher trun it down. if not that trun down the max number of fps you get Its in the control forgot the name ill ask my buddy when e gets off of work he had the same problem.
