As PC makers intensify stockpiling, they are creating shortages elsewhere. Factories have a max productivity, so it is a 0 sum game. If a factory produces 100,000 units of a components each month, and the PC makers soak up 80% of them, that leaves others with only 20%. Of course given the current absurd pricing of GPUs, I think it may be a good thing now where scalpers are not able to get as many GPUs with PC makers grabbing them and selling them at a more sane price. The price for almost all RTX 3080 sold by scalpers is enough for one to get a preassembled PC with a RTX 3080 with a small $$ top up.
