Can you run the game test at your native res? I think it reflects the result better in real world performance since 1 to 1 pixel matching is crucial for great gaming experience. Also it shows the limitation of 256mb vram.
3dmark on the other hand, I always run at default.
Huh? I'm not really sure what this means. My desktop is set at 1680x1024. Doesn't 3DMark automatically set the res down to 1280 when you're running the 3DMark test?
