Hello, I am able to purchase a late 2013 27' iMac for $500. Specs are: i5 3.2 ghz 8 GB of ram 1 TB hdd nvidia 755m gpu It is basically mint condition with no scratches etc. Should I jump on this? I currently have a 2011 mac mini, which is just fine, but the temptation of a good bit more power (casual strategy gaming & web development) is hard. I could then setup the mac mini primarily for my wife's "workstation". Thanks!
