Hi guys I'm in a bit of a conflict in terms of what I should weight out more in buying a new rMBP. I understand that the more RAM a computer has, the more tasks, more programs it can run at the same time. However, with the programs I want to use for the computer, I was wondering if I can sacrifice having more RAM in a computer for a Quad Core processor (and perhaps a bigger screen). I'm a freelance videographer as well as a photographer. That being said, I'll be using Premiere, FCP, After Effects, and Photoshop as my primary softwares. Not all at the same time. Now I've been looking into some refurbished/new models. One option I have is to grab a refurbished (or even brand new) model of the October 2013 15-inch rMBP with Quad Core i7 (Crystalwell), 2.0 GHz, and 8GB of RAM. My other option is to purchase a new 2014 13" rMBP with Dual-Core Intel Core i5, 2.6 GHz, and 16GB of RAM. I'm just not too familiar how the Crystalwell processor works in terms of performance with the programs I plan on using. Anyway, if anyone can input some thoughts, I would really appreciate it! Thanks.
