This is one of the first Nvidia dual GPU graphics cards. It requires a motherboard PCI-E lane splitting capabilities. Most nForce 4 based motherboards will work ( eg. DFI lanparty nf4 SLI/ ultra, Asus A8N SLI ). Most modern motherboards will fail to detect the second GPU, so do your research and check if you have the hardware compatible with this card. The card itself has never been used, just briefly tested before listing it. All in excellent condition.
