I just built a computer, and honestly I didn't need much more CPU than the Ryzen 3600 from my old one. CPUs don't go obsolete the way they used to.
I went with a 7000 series pretty much entirely because my new motherboard said "Compatible with 7000 series. Compatible with 9000 series with a BIOS update." And I didn't want to bother with having to get a loaner 7000 series to do a BIOS update, then swap CPUs.
