Benchmarks: Supreme Commander
Supreme Commander is a graphically intense real-time strategy game that is very GPU demanding. That said, these high-end graphics cards do quite well, as the GeForce 9800 GTX produced an average frame rate of 49.4fps at 1920x1200. The rest of the pack did comparatively well, following a similar pattern as in previous tests.
Turning on 8xAA resulted in slightly wider margins between cards, with the GeForce 9800 GTX still on top of the rest of the cards using a single GPU on board.
