I'm a graphic designer & do a little photography on the side. I run Photoshop/Illustrator/Indesign/Lightroom on a daily basis as well as Safari/Mail. With the price increase for the rMBP, I can't afford both upgrades, but decided to choose either one. I currently use Dropbox/iCloud Drive/External HD aside from the actual computer space, but I feel like at this price point 512GB should be standard. (I can possibly live with 256GB since I can always delete/store files somewhere else). For graphics, is it worth upgrading from 2GB to 4GB with the type of work that I do? I don't do video editing, but I do watch a lot of videos/convert videos using Handbrake. Would be nice to receive input on which upgrade I should go with! Thanks!
