Found a 1080ti on Facebook for £500 and I am on the verge of purchasing it. The seller has sent me over ten videos of the card. These videos include the box, warranty, and it functioning inside of his tower. Is there anything that distinctly separates a fake card from a real one? What are some questions that you would ask to feel more reassured that your money is going towards the advertised product? I am more than certain he is legitimate, I found him on PC parts on Facebook. The group is strict and has various rules that aid in situations relating to scams and fake GPU’s.
