Here's a little motivation to OC the old stuff - Top my score if you can!

(Yes I had to do that.)
You already have the foundation of a nice benching setup, why not use it?
Anyway, I just slapped together a low powered setup for the basics (Daily) and it's doing well but you'd probrably want something a tad more updated.
I'm currently running a 220GE in an A320M board with Ubuntu as the OS. It's a nice, snappy little thing and only issue right now is settling on the exact OS I want to use and that's directly on me.
Basically for any DDR4 setup a minimum of 8GB's with Win 10 but 16GB's is preferred, some even going up to 32GB's but that's probrably overkill here. Have 16GB's in this one running some G.Skill Flares that's PC3200 (B-die) and they are cheap too with nice specs (CL14 set).
I'd suggest (As a daily) a B450 based board for features and so on combined with a Ryzen 3600 (non-X) chip.
Enough cores/threads to do you for sometime to come and it doesn't use too much juice either.
For more such a real OC'ing, definitely one of the X boards such as an X470 or 570 board with one of the Ryzen X chips too.
If you want more cores you know what to do there vs a 3600X as a starting point.
