We are in the market for a new desktop, and are probably going to pick up a 21.5" imac base tomorrow. I have had a MacBook Pro, so I am familiar with the operating system. I know that Macs are not primarily gaming machines, but I'm curious at how it will run most of the newer games on the market. I have StarCraft 2, and would play that, but also eventually will pick up a copy of Windows 7 to run bootcamp for pc games. One of the games I am dying to play is The Witcher 2 for instance...Just kinda curious what others experiences have been. For what it's worth I am really looking forward to replacing our outdated vista pc with an iMac, just hope I can do some gaming on it as well....I also don't need super ultra settings as well. I would be perfectly happy with Medium to High settings as well.
