First off, you don't buy a Mac to play games. While Macs can most definitely play those games, the problem is that they cost way to much to invest in them to play games. The other benefits of Mac are great, but if you want to play games do yourself a favor and get a xbox360 or ps3. But if PC games are your favorite way to play then just get a gaming PC. Will be much cheaper and will play the games just as well.
