I know this is a topic that sometimes irks some, but when comparing the MacBook Pro non-touch bar, will the 16GB of ram get me another 1 or 2 out of the machine compared to just regular 8 GB? I'm going to be doing some Final Cut (will do heavy lifting on my 5K iMac) and Lightroom from the field. $300 seems steep. Looking at the Adorama special of $1349 for 8GB or $1649 for 16GB. I would like to get three to four years out of this MacBook Pro? Upgrading from 2013 MacBook Pro '13 base. On Adorama, they have actually a 8GB touchbar with 2.9 for $1549. It is special code. Thought about that as well, but ram seems like better bang for money.
