That depends which country you are from. In the US used 4080s can be found for around $1,050 - $1,100. Given that your card has damage and PNY is not a brand that offers transferable warranty (not that you'd be able to claim warranty with that damage anyways) IMO it would have been worth it to spend the extra $100 to get a non-damaged card with a warranty. In fact if I look at the sales history for 4080s on eBay, you can see a decent amount going for $925 - $960 in auction or buy it now for those that are patient or have alerts setup. When buying 2nd hand ASUS and MSI are the only two brands where the warranty transfers. Gigabyte can transfer the warranty only if the seller provides the original receipt. Zotac is the worst, wherein they record SN and to which store the card was sent to in order to deny warranties. They don't have a transferable warranty and will refuse to send the replacement to any address other than the one listed on the invoice.
I found the exact listing that you purchased and the seller has a generic listing description and subpar pictures that don't explicitly point out the damage. Typically when you see an eBay seller take shortcuts like this when listing a product they also take shortcuts when testing the product so make 100% sure you verify the card's performance and specs when you receive it. A picture is not provided of the back of the card, so it's hard to tell if the warranty void sticker has been torn and the card potentially tampered with. The upside is that you purchased this card in the seller refurbished condition, which means you are protected by eBay for 30 days. If this card had been sold as For Parts / Not Working, eBay does not provide buyer protection on those purchases and there is almost no way of getting your money back in that situation. In your case, you can essentially return the card within 30 days for any reason regardless of seller policy if you don't like it.
