yes, it's more of a how fast do you want to edit?
look in to proxy workflows, work with something like 720p DNX-HD/prores LT proxys.
depends on the app used ect ..
but it is not an ideal solotion, it will not be fast and without workarounds your using olderversions of osx.
idk if you already have the computer or not, if you do just give it a try and see how it is and relay do look in to proxy workflows if you app dose not have one bult in transcoding the video before ingestion is the game.
if you are going to buy the computer relay look in to alterntives unless your bugets is pushed hard.
