I just grabbed a 5800x for $305 yesterday on newegg. Hardware Unboxed did an analysis of new chips on older boards, and the 5000 series performed surprisingly well on an old x370 board similar to mine thanks to some recent BIOS updates in the past month or so. It looks like my old Noctua CPU cooler will also still work on this CPU, which I also have used with the 1800x and 2700x. AM4 has been a hell of a socket. So again I can add a significant component upgrade without any additional purchases other than $5 for paste. I will also get an additional performance boost from Smart Access Memory given it will be an all-AMD setup, which will probably be worth an additional 5% to 20% depending on what is running.
