Re: Installed a XFX 6600GT 256MB
I found out when I got 6600GT recently several games are CPU limited, such as CSS... I didn't get any better FPS with it than on my 5700, although I could now run with 4xAA and 8xAF and it looked nicer with the DX9 shaders...
Doom 3 / Quake 4 run much, MUCH faster though.
A simple test to see if your game is CPU limited is to run it with no AA and no AF, and then turn AF and AA back on, and if you get roughly the same FPS, it's your CPU that doesn't have enough juice, not your graphics card.
