I’ll echo that you probably want to choose an x3d chip over anything else. The giant size cache lets non-benchmark tasks go much faster.
Is there a reason you chose a two stick ram kit rather than a four stick like your motherboard supports? I used to leave slots open “for when I want some more”, but nowadays when I want some more I’m finding the lower latency stuff is in my price range or I can get a higher speed with a cpu upgrade and end up swapping it all out at once.
If you can get away with a cheap b580 then it’s worthwhile for you to do so. Intel is losing money and fucking up as a business anyway so don’t let their evil actions prevent you from picking their bones clean. No ethical consumption etc.
Consider socking back $20 for some ptm and switching to an air cooler. They’re genuinely not loud, have fewer ways of catastrophically failing and dovetail nicely with the processors built in overheat handling because of their much larger thermal mass.
Consider putting a spinning hard drive in there as well. Of everyone is as versed in the new failure modes of ssds and how to deal with them and having somewhere else your data is stored locally is nice.
Also being able to shuffle something you’re not using off the ssd temporarily is a real luxury, like having a shed.
some hog shit might want 8-16 gigs per thread even, so you probably wanna be on the knowing more specs side (the shape of our datasets determines the future of our compute and things of that nature 
)
