How to buy and upgrade a gaming budget PC in stages?

Question

Computers

if I was going to update the mother and the CPU and GPU (I love Nvidia 4GB).
for example, in the future I plan to first play on am4
on a vidyuhi on a CPU crystal ..
and then buy one and then the second external GPU and then pair
and upgrade the CPU on the old am4 mother from the budget to the top.
This is the most budgetary and phased scheme with am4, right?
and with built-in vidyuhi?
and pair a couple of external video cards and just replace the cheap ryzen with a top one?
What mother to buy, so that it would be easier
in 2-6 years to upgrade the CPU from a cheap to the top of this socket?
am4?

Answer 1

Take the norms mother, percent, and BP.
Buy the rest gradually.
I would advise you to take at least from the new i3, mother gigabytes or MSI on the B series chipset
