After hours of research I've decided to purchase a 27" iMac. I will primarily be using it for FCPX and some gaming. I will be purchasing from the refurbished store on the Apple website. I've narrowed it down to these 2 models. Refurbished 27-inch iMac 3.4GHz quad-core Intel Core i5 Originally released September 2013 27-inch (diagonal) LED-backlit display with IPS technology; 2560-by-1440 resolution 8GB memory 1TB hard drive NVIDIA GeForce GTX 775M graphics processor with 2GB of GDDR5 memory Built-in FaceTime HD camera Refurbished 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 hard drive NVIDIA GeForce GTX 675MX with 1GB Built-in FaceTime HD camera Should I go for the 2012 i7 or would the better GPU in the 2013 i5 benefit me more? I need some help deciding.
