So with the current market price of GPUs. I didn't wanna pay 300 over retail for any of the cards so I decided to get it through Kijiji. The guy mentioned that he never registered it and so I was just able to register it under my account no problem. But I don't have any invoice to upload. Will I still be covered under warranty? as when I added the card to my profile it showed 1000+ days left and its a FTW3 model.
