Crysis Warhead
This game is sufficient to tax even the fastest GPUs without using the highest possible resolution or quality setting—or any form of antialiasing. So we tested at 1920x1200 using the "Gamer" quality setting. Of course, the fact that Warhead tends to apparently run out of memory and crash (with most cards) at higher resolutions is a bit of a deterrent, as is the fact that MSAA doesn't always produce the best results in this game. Regardless, Warhead looks great on a fast video card, with the best explosions in any game yet.

If you thought this game would tip the scales one way or another, think again. Two frames per second separate the cards' averages, and both of our contenders bottom out at 25 FPS.
