I have a six year old i5-2500 and a 10700K is quicker but still not twice as fast as the 2500. Its really not worth the upgrade.

It's still more expensive to buy a brand new Threadripper or 16-core Intel (sic) than this bargain I made some 4 years ago.
I will probably get a Zen 3 platform, once each CCX contains 8 cores (4 is just too limited for my virtualization need, I kinda like that my Xeons are "monolithic").
Obviously this is for programming and shit learning, not gaming, but I can still manage my 60 fps stat with a beefy GPU.
