So I decided that I'm finally done with Windows and I'm planning to buy an iMac. The only problem is I don't have a very high budget, around $800 or so. So I have been looking at Ebay Auctions and basically, here are my options: 2009 iMac 27" with i5, 8GB ram, and a Ati 4850 for $720 2010 iMac 27" with i5, 4GB ram, and a Ati 5750 for $800 2011 iMac 21.5" with i5, 4gb ram, and a Amd 6770m for $730 Are either of these iMacs still good for Internet, Word, Email, Watching Movies, and light gaming? by gaming I mean GTA: San Andreas and Minecraft on OS X. Also how well do these Macs run OSX Mavericks? Should I buy any of them?
