Did your Hellhound have the port covers and PCIe protector/cover? Mine came without them. First card I bought NIB that didn't included them in forever. Wondering if it is typical, or because they rushed mine out the door to fill backorders in September.
Another question: Did your card include the Far Cry: Smurfs go Smurf game?
The Hellhound goes with my 5800X3D like peas and carrots. 6900XT performance at 1080&1440, sometimes more or less depending on the game, in both raster and RT. With less power, and a couple of new features. If the Smurfs game has value for you (collective you), it's $450 for the card. Not too shabby at all.
