I'm looking into replacing my MBP after 6 years. It works fine for non Adobe CC apps, looks great - no marks at all, I take good care of belongings, but I find that using Adobe CC - Muse, Illustrator, Photoshop and occasionally InDesign makes it very slow. Currently have Muse open and none of the others mentioned and I'm still looking at the turning beach ball. When one of the others, i.e. Illustrator or Photoshop are open too, I may as well go and put the kettle on while I wait for a preview in Muse. Also find that resizing the breakpoints in Muse incredibly slow. Trying to decide on whether it is better to buy 16GB RAM or a higher spec processor. Yesterday I got to different opinions in the Apple store. Also using Open Office Calc, Pages, Mail, Safari, (Chrome on the odd occasion). Open Office Calc and Pages are opened as needed. I'd appreciate help from others that use similar programs.
