im the OP, and I have bought the game.
Running it on 800x600, crowd, low detail, no physics
COMP
CPU - 1.66ghz core2duo
2GB ram
nvidia go7300.
Hope this helps.

EDIT: CANT WAIT FOR A NO CD HACK THOUGH.
EDIT2: EVEN AT THESE SETTINGS, i am experiencing some lag at times. but so little that it hasn't affected gameplay yet.
