Although I have a late 2013 13" retina Macbook Pro currently, I’ve realized that I need more RAM as well as a better graphics card in order to be able to use 4K monitors, which I’m very interested in doing. So I was considering purchasing a new 15" retina Macbook Pro, and was wondering what specs everyone thought was necessary.
Considering that I may eventually want to do dual 4K monitors (if that’s possible), I should go for the non-integrated graphics AMD card, right? Max the RAM, and I can live with the 500GB and not the 1TB HD given the massive +$500 it would add. Also it’s not necessary to upgrade the processor, is it?
