Mac Forums

Hi, I have a really (and I mean REALLY) old PC and have been looking for a new one. I have already had great experience with other peoples macs and am now thinking of getting the mini for myself. I was just wondering if its also good for playing games? I know a lot of games are not mac compatible but i can get Parallels desktop or something... Don't ask me why I would want a mac then... I just need windows to play games. Does Parallels slow down a mac or should it be OK? I will use mac versions of games when i can. Windows is for the games, mac for EVERYTHING else. The mac app store has games, i know but do they run fast without lag etc. Oh and will it be able to play Stuff like Call of Duty online with windows users? I will be using the 2.3 Ghz version Any help is appreciated!!!
