I had a 2.0 ghz (3000+) Athlon, 512mb RAM, and a GF4 Ti4200 (128mb) 8x AGP card. I was able to play the game at playable framerates (800 * 600 x 16bit) though on occasions it became very choppy when viewing long distances. (8-10 FPS) I beat the instant action mission with this setup, so I guess the framerates couldn't have been too poor.
