Halo: Combat Evolved

The performance of the system with two GeForce 6800 Ultra cards is limited by the CPU in the first two resolutions of this game, but for the GeForce 6600 GT SLI configuration the performance gain is from 20 to 40 percent. In 1600x1200 the pair of GeForce 6800 Ultra enjoys a speed boost thanks to SLI, but the value of the gain is far from twofold because Halo is too CPU-dependent.

Note, however, that it’s only through the SLI effect that the GeForces can rival the ATI RADEON X850 XT Platinum Edition in this game.
