Hi, I'm looking to buy Late 2009 Model. iMac (27-inch, Late 2009) iMac11.1. Quad Core Intel i5 processor 2.66ghz 16Gb of RAM (compare to 4Gb in standard configuration) 3 TB Ultra Fast Hard Drive (compare to 1 TB in standard configuration) 10.8.4 OSX Asking price $1150. My question would be. Is this a good deal? Also will this work for my photo editting? I'm not hoping to spend $1700+ for a brand new model. This is the price range I want to stay in.
