Gee, Yoshi, you know so much! Maybe you should drop in on Xbit labs and tell every one what they're doing wrong. If I look I think I can find a few other sites that would benefit from you knowledge.

In these bench marks they did all their tests @ 1024 x 768 w/ no AA or AF except on Serious Sam. They also used medium or low settings. Half the games were not CPU limited even at these settings, and the ones that were, had such rediculously high frame rates that it would not make any differance anyone. (Oh noes, I'm getting only 400fps!)
In the one exception Serious Sam 2, the CPU seems to make a difference even with 2x AA and AF, still at medium quality and 1024 x 768 though. Interestingly enough, the 4800+ outperforms the FX57 despite the FX57's 400MHz advantage. The game is multithreaded.
So, in the future, Yoshi, think before you flame, especially if your arguing about video cards and flaming a geek who spends an hour a day browsing a forum dedicated to video cards.
