Splinter Cell: Chaos Theory performance
The Ultra is back up to 12 per cent faster in the Splinter Cell: Chaos Theory test, and it's the only card to break an average of 60FPS at 2560x1600 with 4xAA and 8xAF.
Adding in HDR to the ultra-high resolution mix further confirms GeForce 8800 Ultra's superiority (as if that was ever in any serious doubt). The Radeon's performance drop-off makes it unplayable at this setting.
