Hmm, not sure how accurate this test is.. I just ran the Heaven benchmark (2.0) and this was my result:



This was with maxed out settings at 2560x1600 resolution, 4xAA, 16xAF, extreme tessellation etc, CPU at 4ghz, and 480s at 850/1700/4200..

The stutter index is high, but from what I could discern, the benchmark ran pretty smooth.
