the packaging for this say that it be Windows xp compatible . but it be not ! no driver exist anywhere that will run this card on xp . the installation cd even say `` Windows xp '' on the label . but when you try to install the driver , you get the error message `` driver be not compatible with this os '' . ASUS usually do well with they driver , support , and documentation , which be the main reason I choose this product . but they really drop the ball this time . this may be a great graphic card for Windows 7 or Vista , but I will never find out . I be return it to Amazon tomorrow .
