I had a MacBook Pro 16GB/512 on order through the apple store but then saw all of the videos showing how well 8gb was working. I use Adobe Lightroom, a little Photoshop and for movie editing I pretty much stick to iMovie. 8GB from what I've seen should be plenty. Got my 8GB, used Lightroom, Photoshop and iMovie and everything is lightning fast, no issues with ram. Just now though, I have 3 tabs open on Safari with not a single other application open with one of those tabs running a video. The page keeps refreshing because it is using significant memory. I don't get it, anyone else having this issue with web videos on Safari? I was set to cancel my 16gb order, but may have to keep it now
