We were unable to test the Radeon X1950 XTX at 1600x1200. For whatever reason that resolution wasn’t provided in the game’s menu. In addition, we were unable to test the older GeForce and Radeon cards at higher resolutions. The game has a built-in feature that determines what your current frame rate is. If your frame rate dips below a certain level, it automatically stops the game and asks you to lower your graphics settings. This is what prevented us from getting scores for the GeForce 7950 GT at 1920x1200, and all three cards at 2560x1600.
As you can see, the GeForce 8800 Ultra comes out on top in the overall performance testing, although that shouldn’t come as a surprise to anyone by now. The GeForce 8800 GTX trails by 13% at 1600x1200 and the Radeon HD 2900 XT finishes 24% behind the GTX. The GeForce 8800 GTS cards perform very similarly at the lower resolutions, only at 2560x1600 does the 640MB card begin to pull away.
