I wouldn’t sell my 2080ti for some to say it’s not working right and all the hassle that goes with it Na. My kid is using it brilliant boost from his 1060 6gb.
GPUs get sold every day on the MM and I would imagine very few get any "hassle" from the buyers. There aren't many chancers who would risk losing access by being a scroat. Selling on eBay though is a different story.
