3080 are having some crash issues. I would recommend that you wait for Nvidia to release a public statement acknowledging the issue and if its a hardware design fault or something that can be solved by driver updates. Its entirely possible that they might downclock the card in future driver updates to prevent this and newer batches don't have this problem.
Hahahahah world is too big and I am not vouching for anyone. Just telling that the stocks are their in the market so don't panic and stay calm. People will get 3080s under 80k from reputed sources soon
my friend it is a technical limit ,two pcie power connector would provide 150+150 and pcie slot would provide 375 .Adding a third power connector to pll bit of more power and negligible power bump is utter stupidity
