There have been a couple of other posts on CA ebay gpus with the current ebay plus code, but I thought it was worth highlighting a few options near or at all-time lows.
6600 for $272 delivered is a standout, probably the last decent card we're likely to see sub $300 for a while.
Gigabyte Eagle RX 6600 $272.22 (previous low $280.02)
Intel Arc A750 $358.02 (previous low $349 + delivery for the Asrock model)
Previous deal on the Gigabyte Eagle RX 6700XT for $467.22 is still active
Asus Dual RX 7600 $404.82 (ATL?)
Galax RTX 4060 Ti $553
Gigabyte Windforce OC RTX 4070 $857.22
Free delivery. Quantities all above 10 at time of posting.
Currently have an old RX580. Was looking to start learning Ai/ML so need Nvidia. Is 4070 a good option?
