Supreme Commander
This game has gotten less power-hungry with age and by comparison with some more recent games. But Supreme Commander is still interesting and inevitable for network gaming. On a battlefield, but without too many units at the front (to keep from being too limited by the processor), at no time was the GTX 280 able to surpass the 9800 GX2, whose lead was as high as 39% at 2560*1600. Yet the GTX 280’s results weren’t what you’d call ridiculous, remaining approximately 45% above the 9800 GTX and the 8800 Ultra, even if it’s fair to have expected better.
