I am planning to upgrade from my 2010 iMac 27 inch with i3 to a newer model. I am doing some photo editing and light video editing of our home movies on iMovie. I like to play a few games like Civ V and Diablo III once in a while but don't game on my iMac much. I will add more ram to the new iMac myself. Here are the 2 choices I've narrowed it down to. Please help me decide! Option 1: Refurbished (From Apple) 27-inch iMac 3.4GHz quad-core Intel Core i7 Originally released October 2012 27-inch LED-backlit display with IPS technology 8GB memory 1TB Fusion Drive NVIDIA GeForce GTX 680MX with 2GB Built-in FaceTime HD camera with AppleCare I'm at $2,322 shipped to me Option 2: 2013 imac 27 inch 3.4GHz Quad-core Intel Core i5, Turbo Boost up to 3.8GHz 8GB 1600MHz DDR3 SDRAM - 2X4GB 1TB Fusion Drive NVIDIA GeForce GTX 775M 2GB GDDR5 with AppleCare $2,321 shipped to me from B&H Photo Am I really splitting hairs here? Are both of these iMacs going to perform about the same for my needs? Thanks so much for any input you have.
