Alright, so I just bought my Aluminimac a while ago (about a month). Iv'e poked around the web, but I haven't found any good free 3d games to really push my mac. One of the reasons I got the upper 20" was for the graphics card, but so far it's been a waste of $300. Does anyone know of any good free 3d games to try out? Before someone says by Battlefield or Madden or something keep in mind, I just got this thing. I will say I'v found a good 2 game, EV Nova, which I'm currently flying a Vell-os Arrow in .
