There's a problem. We don't know who made it. It doesn't say an card vendor's name (like EVGA and ASUS) on the card or an PC vendor's name (like Dell and HP) on the auction, and it does not have an real NVIDIA logo so I don't think it's real. It may work for a day or a week but then it will stop working, and then you don't know who made it to call customer support.
Some person in America who speaks Chinese probably got these really cheap and had them sent to him and he sold them to various outlets. Wish I spoke Chinese sometimes!
