So if i get something like an msi meg x570 unify motherboard for £250, will this support a 3700X, 3900X, 5900X, 5950X?
The unify appears to be what im after - has reasonable onboard sound (Realtek acl2200) so no DAC / internal soundcard required, has multiple NVMe slots and Wifi.
I then need RAM (£220) and a new case (~£100 or are cases more?)
I then drop in a 3700 / 3900 and can get a 5900 / 5950 at a later date along with a cooler or just use the generic one that comes with the 3700X / 3900X
