Something is very definitely wrong.
It is not new and untested, it's been in use since 2018.
Personally, I think its less due to these and more due to people using bots to buy up stock for scalping. The same stocking issues have happened for the new Xbox and Playstation, and even for non-tech hardware, like the newest Warhammer 40k box set. The bot scalping issue is just becoming more pervasive.
Back then these highend-GPUs used to be prestige projects that mostly existed for the marketing of "We have the fastest GPU!", the real money on consumer markets was made with the bulk of the volume in the mid-range.

But on a serious note - why are they doing so? Surely, they have good predictions of supply and demand - why are EBay resellers reaping the profits from the gap between the two? Why aren't these cards retailing for $1000, with price reductions happening as demand drops below supply?
And I do not feel sorry for them.
