Hmmm.... Installed the 6800 GT and I played Stalingrad on Call of Duty. It dipped as low as 8 FPS (1280 by 1024, everything at MAX.) It's roughly the same as my old 9600 XT. In addition, there were some graphics issues on Stalingrad, weird blobs were appearing once where bullet impacts from planes should have been. FIX YOUR DRIVERS, APPLE!
