What’s more important for editing 4K video? Upgrading the RAM, graphics card or processor? Main question is between 16GB RAM vs 32GB RAM and Radeon Pro 555X vs 560X. Buying 2018 MacBook Pro for video editing and would appreciate some input. I use Adobe Premiere. The thing that is most important to me, is being able to play the video as smoothly as possible while I’m working, without needing to render. I don’t mind waiting a bit longer for exporting. I’m also happy with 256GB SSD, as I’ll end up using external storage. I use Photoshop as well and often keep it open and switch between both apps. I also tend to leave a lot of browser tabs open. The most I’ll spend is around $2750 total after tax. I’m looking at the Apple Refurbished section. I bought a 2018 MacBook Pro from the refurbished site with 2.2GHz, 32GB of RAM and the 555X graphics card. I tested some 4K video in Premiere by placing four 4K clips onto the screen at the same time, it just froze and did not play. Even one 4K video in the sequence is not playing smoothly and turns up the fans. Also along with other things running it was using 20-30GB of RAM. I was hoping/expecting a bit more out of a 2018 laptop. I want to get something that’s future proof, 4K video was my concern, I’m sure I’ll be ok with HD but things are moving toward 4K. If I return it and only get 16GB of RAM but upgrade to the 560 instead, would be worse or better? Would I need to upgrade to 32GB RAM and 560X? How much of a difference is there between 555 and 560? I saw benchmarks but it was for 2017 cards and I do not really understand it. Real life experience would be helpful. What would do the job? What would be best? 2018 2.2GHz, 32GB of RAM and the 555X (What I’m planing to return unless nothing here is much of a jump) 2018 6 Core 2.2 GHz 16GB RAM and 560 (New) 2018 6 Core 2.2 GHz 32GB RAM and 560 (If I can find it on Apple Refurbished) 2018 6 Core 2.6 GHz 16GB RAM and 560 (New from B&H) 2017 4 Core 3.1 GHz 16GB RAM and 560 (New from B&H with 1TB SSD that I don’t care for, doubt this is better anyway) Thank you very much for your input.
