Choice of mat. boards (int/amd) to upgrade cpu(2-8 years later)+install two gpu?

Question

Iron

so that the socket does not become obsolete so quickly - take amd mp?
Heard that AMD releases new sockets less often?
and that within 2-8 years later it is possible to easily replace budget ryzen am4 with a top within the socket?
and who was updated?
does it make sense first on the built-in vidyuhi
and then on the nv760?
and then two nv760 paired?
Is this a no-brainer upgrade?
I’m just going to assemble for a year on the CPU + MP + RAM,
not counting the vidyuha and the screw
, but I want to use such a system unit to play World of Tanks on a full config + ultrahd,
well, a little more for the video conferencing server and the site server ...
so the little things animation and database ...
and of course, watch extremely high-quality video films on a huge monitor!
