Pretty much every card out there is selling. I sold a gtx 1070 on ebay recently for over 300 bucks. I'd actually intended to upgrade from that to a 2070 I'd bought used, and ended up finding a 6600 xt at close to msrp, so bought that and sold the 2070 for over 500. Now the 6600xt is out of stock mostly and the ones like I paid 439 for are going for 600+. This graphics card market is nutty, and cards are either hard to find or very expensive.
The card you are asking about is probably getting produced, but pretty much any card that is powerful is getting snatched up.
