Hi guys, I've been thinking to get a rMBP 13 for my editing works (Lightroom, Photoshop). Could you advise which rMBP 13 I should go for? Will basic CPU + 16 GB RAM enough for this? Note: Reason I am getting rMBP 13 is for portability and I have a PC with 27" monitor to use when I am at home. Thank you.
