As the title suggests I bought a used 1070 on ebay for $270 CAD, the description of the card said that "Used approx. 2 years. Pulled from working system. Includes original box as photographed" I contacted the seller about warranty and stuff and since the seller had done a bunch of selling and good reviews I figured it was a good deal.
After I bought the card the seller would not reply to my messages and I had to make an inquiry on another card he had with a different account. This is where I learned that these cards were mining cards and the whole "pulled from a working system" was just him testing the card on a working system and not actually being used in that system. I know this is my fault for not doing more research and stuff but how worried should I be about this card? he states that undervolts the cards and didnt use a special bios for the cards. Also, does this give me justification to ask for a return? or am I stuck with the card? Thanks!
