Dont know who to ask this question, and tis the first place that came to my mind. I have 2 GPU's both 270x vapor-x by sapphire and there both in working order just used them around 20 min ago and i didnt expose them to static... I am woundering if i sell my card on ebay and when the buyer recives the item and he somehow breaks it and says that it was like that before the shipment what can i do? (Selling For 120 USD)
