Absolutely yes.
The customer is voluntarily willing to pay for it, so it is fair.
If the customer pays for it, is because he values the hardware more than the money he's paying.
The real question is who should get the hardware: you, to play a game, or somebody who thinks he will create more wealth than the cost of the hardware?
Is like a piece of wood. Who should buy it? You may buy the wood, to make a barbecue, and profit 1$. Somebody else may buy the wood, to make a house, and profit 1000$
Society is better by giving the wood to the house builder, because it gives back to society 1000$ more than the cost, and you give back only 1$
The price informs that the good is better used by somebody else, and if somebody else gives back to society 1000% more than you do, they should get the good, and not you.
Nvidia does the right thing by selling it to the best bidder. You are the selfish greedy one. You want the wood, even if it costs a house to the rest of society.
