The last batch of tests we ran using the high-end graphics cards focused on 8xAA/8xAF performance. At 1680x1050 the Radeon HD 4870 X2 was still the fastest graphics card, as the broken (no SLI) GeForce GTX 295 ended up behind the GTX 275 and GTX 285 graphics cards.

The Radeon HD 4870 X2 opens up its lead over the GeForce GTX 285 at 1920x1200 averaging 14fps more. This time the Radeon HD 4890 performed within 2fps of the GeForce GTX 260, which made it 12fps slower than the GTX 275.

The Radeon HD 4870 X2 remained impressive with 53fps at 2560x1600 with maximum in-game quality settings enabled. The next fastest graphics card was the GeForce GTX 285 with 41fps, while the GTX 260 managed 33fps, followed by the Radeon HD 4890 with 32fps.
