Does Zen3 make the 8700k/8086k/9700k redundant or is high quality processing hardware now just affordable? I'm thinking of buying an 8700k rig second hand for around 1-1.4k. The only issue in my mind is now Zen 3 is here, is going down this road kind of a meh path compared to just building a new rig with a a 3700x or something.
