I'm looking to get a bit more portable and go to the 13" ntb macbook pro. I'd be downsizing from a 2.7 GHz 16gb ram, early 2013, 15" mbp I do photoshop, sometimes video editing (less than 10 minute videos), browsing, email, etc. Is the baseline (8gb ram) sufficient for what I'm looking to do or do I need to shoot for the 16gb version. Will I experience a drop in performance going to the new 13" with 8gb ram? 16gb? All responses much appreciated.
