So yeah, this benchmark kinda blows, doesn't even have a full screen option so those with 2 card setups can't take advantage of it, but on my 6950 shader unlocked at default clocks, I got a 5400~ score and it said the performance is very high so I guess it doesn't need a whole lot.
Here is a FRAPS capture at 30FPS, switch to 1080p and see the supposed max out setting :P :

Have fun!
Update: new version 1.02 supports full screen and borderless window mode, crossfire and sli don't work though.
