Notes

If you recall our original BioShock performance article, the performance between the GeForce 8800 GTS 320MB and 640MB was very similar – all that changes once AA is enabled. As you can clearly see, the GeForce 8800 GTS 640MB card pulls ahead of the 320MB board, running 19% faster at 1600x1200. The GeForce 8800 GTS 320MB can’t even run BioShock with 2xAA at 2560x1600; it lacks enough memory to run the game with AA and literally locks up the game.

The GeForce 8800 GTS 640MB puts up very respectable numbers at 1600x1200 and to a lesser extent at 1920x1200, while the GTX board runs anywhere from 19-28% faster than the GTS 640MB at 1600x1200 and 1920x1200. We also see SLI scales up to nearly 30% in some cases.
