Got a MSI B550 Tomahawk, R5 3600 (2020 edition), 1TB ADATA nvme, evga 2070 super, re-used my old Noctua NH-D14 which I bought back in 2014. The Noctua company sent me a free motherboard installation kit (kudos to them). No o/c'ing with the exception of memory, 4 sticks of F4-3600C16-8GHVK, which run at 3733 (used DRAM calculator). In a Phanteks P400A case, the CPU temps at light load are 33-34C, under stress (Cinebench, 3668 score) - 71-72C. So far so good, I upgraded my 6 year old i5 4690k (o/c to 4.3Ghz). The primary goal of the machine is for gaming (pubg, total war series) and running VMWare. I used to get freezes/CTD in pubg, now it is smooth sailing with the same video settings.
I almost bought a 3900x, but changed my mind when Best Buy refused to price match the price to the one from Microcenter :-) Glad it happened, look forward to the next gen AMD processors in 2021 supported by B550 platform.
The Ryzen balanced plan works great, the machine falls asleep and wakes up very fast. The boot time is pretty quick, I am on a 2020 May bios release.
