I gave up playing games when I switched to mac in 2005. I have a mac pro and just purchased the radeon 4870 from the online store. I got it to keep my Mac Pro Classic kind of "up to speed" and wanting to get more horsepower than what I got with the lowly nvidia 7300GT. So, now I figure I can actually run games on my computer. The thing is, I don't know what any good games are. What do you guys play?
