I am still waiting for a decent priced elusive 3080 which could be a few more months. By that time the 5900x would be 7 months old (haven't got one of them either). I looked at some bench tests of the 10900k on an nhd15 with all cores at 5ghz and temps at up to 70oc. I think that's pretty good. Thinking of sticking with Intel now for the single core performance. I play some games which will benifit from single cores on direct x like planet coaster for example.
