FarCry2

In Far Cry 2, the HD 5770 manages to outrun the reference HD 4870 card but only at 1680x1050 without AA. Both cards are quite capable of spinning Far Cry 2 at 1920x1200, with and without AA. Once you push the resolution up to 2560x1600 with 4xAA, both cards drop below the magical 30 frames per second mark.

The HD 5850 manages to outrun the GTX 285 in every single test, where the highest performance gap was around 20%. Furthermore, The XFX HD 5850 does a good job in keeping up with the Sapphire HD 5870 1GB, which is a nice feat especially considering that the highest performance difference is at 2560x1600 and 4xAA 8XAF, and the difference still amounts to 22%.

The XFX HD5750 scores almost identically to the HD 4850 512MB, lagging behind by a few frames throughout the test.

The HD 5770 does pretty well, and without the filters on, it's 4%-10% slower than the famous HD 4870. Turning the filters on results in 15%-20% difference.
