Pretty old card but huge amount of vram and good double precision. 32 dollars with free shipping seems too good to be true but they have sold multiple with good ratings.

edit: ordered 1
when i posted this it said "more than 10 available / 7 sold" when i went back i noticed it was 8 sold, so i was like okay screw it ill jump on and find out, and now it's 9 sold. I wonder how many they have.
edit2: 17 sold in past 24hrs... still says more than 10 available i think this auction was done in error and i doubt ill get one, at least there are a bunch of buyers so i feel like ill get some safety in numbers
