Call of Duty 4: Modern Warfare
We tested Call of Duty 4 by recording a custom demo of a multiplayer gaming session and playing it back using the game's timedemo capability. Since this is a high-end graphics card we're testing, we enabled 4X antialiasing and 16X anisotropic filtering and turned up the game's texture and image quality settings to their limits.

Thanks to a recent change to Nvidia's drivers, we were (finally!) able to test at 1680x1050, even though that's not our display's native resolution. Consequently, we've chosen to test at 1680x1050, 1920x1200, and 2560x1600—resolutions of roughly two, three, and four megapixels—to see how performance scales.

Now you can see why three-way SLI is billed as a solution only for those with large displays. At lower resolutions, three-way is slower than a dual-GPU config. As the resolution rises, though, its performance remains steady, until it takes the lead at 2560x1600. Notice, however, that two 8800 Ultras are still pumping out over 70 frames per second at the top resolution.
