I game on my Intel Mac Mini (Core Duo 1.66 GHz). I did upgrade from 512 MB to 1 GB (on my own using the putty knife method) and that went very smoothly. Entire process took about 10-15 minutes I'd say. As far as the point here... I game on this machine (both under OS X 10.4.7 and Windows XP SP2 with Boot Camp). While I have sometimes seen some performance issues (in Star Wars Galaxies, for instance, under Windows) - the RAM upgrade seems to have fixed pretty much all the performance problems I had when I ran the game with the stock 512 MB of RAM in the past. I see all these posts about people running on iMacs with 256 MB of RAM, etc. and so on and so forth. Those posts lead one to believe that you need some real high-end Mac to game with. Maybe that's true for certain titles that are rather demanding (and there's nothing really wrong with that I suppose). But, I would like to say in my own experience, 99% of the games (Windows and Mac) I've thrown at it have run great. Some games I've played on it: Windows: Star Trek Armada 1 Star Trek Armada 2 The Movies Star Wars Galaxies Star Wars Empire at War Star Trek Elite Force These games run great in my experience. I have tried some others not listed here, too. Mac: Jedi Knight II: Jedi Outcast (with the new patch) Pac the Man X Solitaire XL Age of Mythology (a PPC-based game for now) All of these run great, AOM is a little slow at times but very much playable. I also tried Elite Force 2 (PowerPC only for now). The performance was very bad in this game (due to it being a non-universal binary I believe). It was playable but just barely. Anyone else with an Intel Mac Mini please post your experience/comments/config? For the record, I also have a 1.42 GHz 1 GB PowerPC Mac Mini G4 and it runs well too. It runs Civ 3 (not the Complete edition), Jedi Knight 2: Jedi Outcast, and other games fine (including Elite Force 2).
