Greetings all. I recently sold my Nvidia Quadro FX4000 256MB AGP graphics card on Ebay to a guy in Germany (I am in UK). Used the standard Ebay description tool which displayed it as PNY NVidia Quadro FX4000 256mb AGP card. My question is: are there 2 varients of this card ie Nvidia and PNY? The guy is stating that I have sent him an Nvidia Card as opposed to a PNY card and is requesting a refund. I sold the card in good faith (using the Ebay description tool) thinking that there was only one varient and the picture I took is exactly like the PNY varient too so I thought I was selling one in the same? I would appreciate your views guys. I think maybe this guy is trying it on? Many thanks.
