Hi guys, I'm in the market now for a new rMBP. Figured I'd upgrade from my 2011 15" MBP since it's on its last legs. I'm deciding between the top end 15" rMBP or the maxed out 13" rMBP (3.1 Ghz dual-core i7 + 16GB RAM). Anyone here opt for the maxed out 13" rMBP i7 instead of the top end 15" rMBP? I'll be using Photoshop CC + Lightroom 6 + countless heavy PDFs for research (varies from 100mb ~ 200mb in size).
