Currently I've got a MacBook Pro 15" (mid-2010, model 6,2), with 8 GB RAM, 2,5 GHz i5 Processor and Intel HD Graphics 288 MB video card. Seeing as it's 5+ years old, I really need a new one, reliability wise. It freezes when I'm working and has it's random shut-downs/white screens/black screens. (Link to specs)
But, I've got a dilemma. I'm a graphic designer and need to work with Photoshop, Illustrator and Indesign, so performance is needed. BUT, I also am working on my masters degree, which requires portability, internet and MS Word (no more).
I don't take on too many design projects seeing as getting my masters degree takes up a lot of my time. But, I do need to work with big Photoshop files (2+GB) which my current granny-macbook can't handle properly anymore. (specifically CPU and GPU are busy chewing on the size documents I work regularly on)
How can I evaluate my workload to better decide if
Retina 13" with 3.1/3.4 dual-core Intel Core i7,
16 GB RAM, 512 GB SSD, Intel Iris Graphics 6100
Retina 15" 2.8/4.0 GHz quad-core Intel Core i7, 16 GB RAM, 512 GB SSD with
Intel Iris Pro Graphics + AMD Radeon R9 M370X with 2 GB vRAM
What do you recommend? Is the 13" performance OK to last roughly 2 years of heavy Photoshop use or do I need to get the bigger and thus less-portable 15"? Is the 3,1GHz dual core 13" as good as the 2,8GHz quad core 15", or at least a lot better than the one I have now?
