Far Cry 2
We tested Far Cry 2 using the game's built-in benchmarking tool, which allowed us to test the different cards at multiple resolutions in a precisely repeatable manner. We used the benchmark tool's "Very high" quality presets with the DirectX 10 renderer and 4X multisampled antialiasing.

Our first real game test shows us just how close of a contest this is shaping up to be. The 4890 OC leads at the two more common resolutions, but the GTX 275 steps into the lead at our four-megapixel peak res. We see this same pattern in the match-up between the GeForce GTX 260 and the Radeon HD 4870 1GB, so it's not an unexpected result.
