is it worth torturing 4 GB? Maybe it's time to give them to gamers?
Yes I agree however how you tried to sell any GPUs to gamers lately. It seems that if you are selling a RX 470/480/570/580 then almost every buyer that asks about it, says "Have you mined with this GPU?"?
You got no choice but to bite the bullet and just admit that you mined with it because if they check your other listings and see different models of RX series GPUs with different manufacteurs, they will be suspicious. If you were a gamer, why did you need 10 GPUs. Obviously they were mined with.
Most buyers don't care, they just want to make sure it works before hand and they give you the money and are happy. Other want to make sure that the fans are working at least. While others basically offer you "$20 because I know you mined with it" and lowball you.
