Well, It's not an official Benchmark, but I ran the video test in Company of heroes and I got MASSIVE improvement over my previous set up.
Old:
AMD X2 4400+
2 GB RAM
Two 7800GT's in SLI
Nothing Overclocked. I had to run at 1200x1024 at medium/high settings to get reasonable frame rates. Anything higher had noticable studder.
New:
Same box with an single eVGA 8800GTX. 2048 x 1536 at complete maximum quality and AA.
Max FPS 160
Average FPS 61
Minimum FPS 33
I'm extremely happy with the performance of this new board.
