I don't really know a THING about Mac gaming. I'm getting rid of my current LCD iMac, and getting the 800mhz/superdrive model. The graphics card is the 32mb model, vs the more expensive 64mb in the 17". Is this machine sufficient for gaming, and moreover, will it keep me going for 2 or 3 years, assuming I max out the RAM? My old 500 mhz icebook used to run THPS2 fine with 128 mb of RAM (granted, it was in OS 9), but my 700 mhz G4 iMac can't run the Return To Castle Wolfenstein demo at more than 10 fps. I don't wanna get stuck with a piece of crap. Suggestions? Opinions? Thanks
