I'd like a 15" MBP with a retina display for photo editing, website stuff, and consolidating all my other computers into one system. The lowest priced Apple refurbs are $1600+. After doing some research, I'm thinking about finding a late 2013 with the 2.6G i7. Checking on geekbench, those 2.6G 2013 models are very high on the benchmark charts. Higher than some brand new 2015 MBP 15" The 2013 seems to look like the best bang for the buck in a used MBP 15" Is there something I'm missing here?
