It's different for every game.And it also depends on how fast the rest of your
system is.
In Far Cry for example,I tried running a benchmark at 1024x768 w no AA and
Aniso at 8x. It was in the high 20's. Tried at 4X AA and 0 aniso and it was in
the high 40's to low fifties. Wit AA and Aniso both off it ran in the 70's.
I thought it was kinda slow though. My setup is:
CT-VNF3-250 nForce 3 754 mobo
A64 2800+ CPU
512M PC3700 DDR
Nvidia Geforce FX5900.
