Something is up. the price for a 3090 is 457
on eBay the cheapest one is 699
if I sell my card on eBay fees would be 150
I would clear 550 and worry about issues
457 is tempting price
I have 20 cards
Of course, I envy that the prices for video cards are so high in the USA, but even if you sell 20 PTX 3090 video cards, you will have to pay extra and buy 20 new video cards, which now have nothing to mine with such a large payback. And commissions on eBay are very high.
