I have 2 potential used iMacs to pick from: 1. 2013 27 base model for $1500 local pickup - has 10 months of warranty left. 2. 2012 27 i7, 8gb ram, 1TB 7200 rpm (not fusion), and GTX 680M 2GB for $1600 approx 3 months of warranty left. I do some light gaming like WoW and D3. Plan on using an external TB 512GB SSD with either one.
