I recently played skyrim, and was noticing a significant loss in frame rate on even medium settings. I upgraded to the 11.11 update that came out yesterday, but it hasn't changed much. I ran 3d Mark 06 again for the first time since march of 2010 and noticed a significant loss of frame rate for all of the tests. Anyone have any clue?

clean the dust? what are the temperatures during benchmark? check that your PSU isn't giving out (check fan is going and approx exhaust temp if you don't have a sensor on it)
that actually happened to be the problem. I completely gutted it last night and cleaned everything (new thermal compound etc). runs better then it ever has
