Just FYI, the version that's on twitch isn't choppy. Here's the link (the Youtube video starts at 21:23):
Twitch is the world's leading video platform and community for gamers.

I really don't see the point right now honestly. I'm still running a 4790 (not even K and overclocked) and don't see any issues at all. I can still run most games on high or ultra without even going over 50%. Most of the time I have issues, it's due to shit optimization and the processor I have wouldn't do a damn thing to help. It seems like software just hasn't caught up to technology. My daughter's computer (which was my old gaming rig that I built 8 years ago) still runs every game on the market without too many compromises.
What I have found makes a huge issue, is RAM (16gigs minimum), a decent GPU (1080gtx for me and 970ti for my daughter), and a SSD drive. I also found decent gains by running a second crappy gpu (non-sli) for my side monitors and only the main center monitor as the only thing attached to my main card. Other than that, I am obsessive about keeping a clean PC. I don't allow bloatware. I don't allow automated things like problem reporting. I don't allow autoupdates (although I do consistently update). I don't allow tracking of any kind and have a DNS level ad blocker so my PC never needs to process ads.
This matters so much, that when I browsed a friend's computer that had a threadripper and SLI x2 2080ti's, I didn't notice anything major in performance. Sure, he got better frames on average. However, I would much rather spend the extra $3k on my house than on getting 20 extra fps. (disclaimer, I was able to get him up to holding a steady 140fps by killing 90% of the useless crap his PC was constantly running).
It has led me to my long standing opinion that your best bet is to build or buy a well balanced PC, do a clean install of the OS (removing any partitions and bloatware), and simply keep a clean house. It puts you in a much better price/performance balance that you just can't reach with a $1,000+ processor. Now this might be different if I was a streamer or doing anything intensive like graphic design or video editing. I don't though. I just game and watch videos.
(EDIT) I also don't mess with 4k or use a big monitor. I am only on a good quality 27in. If I did use a larger monitor, I would either need to get 4k or deal with a significant loss in detail. 27in seems like the best I can do without needing to cross that line.
