Well that sucks, at least if you sell it on the MM you can offer support afterIts not transferable. May have been in the past but its not now. I just went through the details when I sold my 2080ti. You can unregister the product from your account but they have added text now that says that once you do they will not provide support for the card and it can not be re-registered to another person as the serial is effectively deleted from their database.
