A commodity is worth whatever the market is willing to pay for the available supply and crypto-miners are willing to pay those prices because they still turn a profit from it so gamers who want their shiny new GPU now have to compete with them for the available supply.
People have built $10 000+ gaming PCs in the past using high-end motherboard with PLX switches on $1500+ server motherboards and $1000+ matching CPUs to fully support quad-SLI, not exactly new to people who want the fastest gaming box they can possibly throw together no matter the cost.
1. Yes, yes it's worth whatever the market (as in, fools pay) bla bla bla, BUT that does not mean those willing to pay any price are not insane. Someone can consider worth paying 1 mil USD for a candy bar, that does not mean he's not insane either... having lots of money does not guarantee sanity at all.
2. It will be new, when 1 GPU alone will cost $10000, not the entire PC... because if I'm not mistaken, I think we have already reached the new crazy at $5000 on some extreme versions of the 3090 and if not, then some version of 3090 Ti will surely reach that.
$10000 for a whole PC is nuts, $10000 for only one component, a GPU even, is lunacy asylum territory.
Let me put it this way, would paying for the lowest entry GPU (think RTX x060 or even RTX x050 class from nvidia) not be insane if the price of that GPU would be $5000?
Which means from RTX x050 up to RTX x090 Ti you can get up to $10000.
I don't care about economic explanations and excuses, the issue is sanity here. And it's not debatable. This is the direction we are headed, unless something major stops this trend...
