I'm trying to decide if I need to spend the extra $200 for the 16gb RAM option. I'll be doing some action cam video editing in iMovie and GPS mapping using Garmin BaseCamp software, along with all the other typical PC tasks. I might also have quite a few browser tabs open at the same time. Would 16gb of RAM be beneficial to me at all, or would 8gb suffice? Being that you can't upgrade the RAM later, I just want to make sure 8gb will be suitable for my needs.
