All four graphics cards are being tested with the default AMD and Nvidia frequency specifications using the latest available drivers at the time of writing. Our gaming test suite includes Alien vs. Predator, Crysis Warhead, Battlefield Bad Company 2, Just Cause 2, Metro 2033 and S.T.A.L.K.E.R.: Call of Pripyat. Each game was tested using the maximum visual quality settings with some level of anti-aliasing/anisotropic filtering enabled when possible as detailed on each benchmark page.

To measure performance we are using Fraps, recording the minimum and average frame rates for each pair of graphics cards. As in our previous GPU shootout, we are including a frame rate timeline that should suggest how each graphics card performed at a given moment compared within the benchmark run.
