.It's time for you to upgrade to 190.38 now too. In it you can go to the nvidia control panel and force it to run certain programs at full power no matter what. The new tech is called adaptive power control. It's under 3d settings.

EDIT: NOTE: for those not in the know about this problem, some GPU cards have a '2D clock' feature (energy saving) which can kick in unwanted, certainly for those amongst us who want that card Folding at full speed at any time (meaning with the '3D clock' speed setting) !
