People forget that these cards can do what they're designed to do, which is game. That's my intent, though I risk having having artifacting because it was mined on, so I risk getting a graphics card that effectively useless to me, hence my lower offer. I used to have a GPU farm, and after I broke everything down for sale and tested it, many of the GPUs failed to be game stable, or started showing signs that they would artifact in games, so I had to bring down my price on a lot of it.
But it is your equipment, and you can choose what price to sell it for. GL
