Now, a lot are complaining about this, and from the links and google searches i've seen, there's been no actual benchmarks. Can anyone please base their reasons for why this isn't a great GPU for games? I'd only want to play Portal 2 and a few 2005-ish games with a retro collection too, so its not going to bother me. Who really is going to shell out more money to play Black Ops on a ultra high setting? The main majority of games on the Mac App Store will run perfectly, so I don't understand the massive issues regarding this. If you want a games machine, buy an XBOX, or play good games on an iOS device But that's just my opinion, i'd love to hear some good legitimate reasons against this.
