depends!!!
if you have an rtx 2080 ti
and you are a HUGE fan of ac origins/odyssey and total war games
and you have like 1000$ you really want to spend and cant find any other way to get rid of it
than you can go for a high end ryzen or an i9 if you want to stream also or i7 (depending what you like more)
if you have something like a 1080 or any gpu from amd i would say its not worth the bother
