I have a mid 2010 quad running High Sierra - I use Illustrator, Photoshop and Indesign daily... what I'm curious about is how much time I have left to keep this desktop before either Apple or Adobe moves to the point where I can't use this tower. It's not about speed, its compatibility. I know at some point this 5,1 won't be OS X upgradable and that Adobe will make older OS Xs outlawed - they've done it three times before (been on Mac/Adobe since 1989). I only upgrade hardware when they put their standard issues on the back of my neck )
