We tested in the Branchester scene of Serious Sam 2 with the Version 2.070 patch applied. All testing was done using the HOCBench utility at resolutions of 1280x1024, 1600x1200 and 2048x1536. In one case we had 4x AA and 16x AF enabled and in the other we had enabled HDR along with 16x AF.

In both cases the 320 MB 8800 GTS ends up performing quite less compared to the 640 MB version, however, with HDR enabled performance on the whole is much lower. The combination of HDR and 16x AF results in a large performance penalty at high resolutions, and overall the 320 MB 8800 GTS is the lowest performing part in the second test.
