up here, when people sell used, they expect nearly-new-prices because N years ago it was an awesome card. basically they want a refund. very few are reasonable. i see used SSDs being posted for more than a new one all the time! no idea if anyone buys them, or how far down they negotiate, but it's messed up.
no boosts around. i could get a triple-wide 570 for $125 if i wanted to.
