I already bought Asus Chrosshair 8 Hero and 16GB (2x8) DDR4 3600mHz ram kit back in august, after watching reviews and buildzoid's motherboard breakdown

(where he mentions that VRM on that board is so efficient that 3950x could be run without heatsink on VRM and only overclocked 3950x which would take 400A might give VRM's enough load so they would be needing heatsink) - was waiting on cpu (due to shortage) and bios fixes but now when both cpu's got like 50gbp off the inital price i still can't decide which one to go with, i guess will need to do as my friend says: get the cpu of amazon (as i have gift card to use for purchasing lol) and if it doesn't perform how i want it - return get money back and buy other cpu....maybe such option should be viable because i know that software i use for hevc video encoding can max out 8 cores 16 threads (tried with friends ryzen 3700x) but i don't know if it goes above that as none people i know have the mentioned software nor cpu's with more than 8 cores...
