I have never been so torn about a new MacBook Pro purchase. I generally upgrade every 2-3 years, and while my 2013 Retina MacBook Pro is still a great performer, I am in need of a better GPU and larger internal drive. After briefly considering buying a refurbished 2015, I finally decided to pull the trigger on the 2016 model. Unfortunately, I haven't kept up with hardware in the last few years, and I was conflicted on which model to go with. I knew I didn't want to spend over $3200, and so I decided to grab the 2.6 configuration, with the 1TB drive, and the 460. It came in right at $3199, and hit the sweet spot for me. That being said, should I have gone with the 2.9 and gotten the 512 and the 455? It's hard to find any direct comparisons out there, so if there are any savvy hardware gurus that know the answer, I'd greatly appreciate any insight.
