I'm getting a new 1.33 GHz Powerbook for myself in the next few weeks and am looking at some games. (College students need games, yessiree!) I'm definitely getting UT2004 and am trying to decide on a second game. My choices are Halo and Medal of Honor Gold (I think that's the name) with MOHAA and Breakthrough Expansion. I'm wondering how well Halo would perform with 1 GB of RAM and only a 64 MB GPU. Seeing as it's a port, and probably a poor one, it would require more system resources than the platform it was originally developed for. I'm just looking for a good single-player FPS to go along with my UT package.
