I buy this to upgrade a older computer that have no graphic slot , so that I could use a wide-screen monitor that the integrate graphic could not support . it work well for that to some extent ; the option be good , the image be great . however , it be very slow , I think actually this be a limitation of the PCI slot . however , the thing that be the most aggravating be that it frequently blank out entirely , leave you with a black screen . it will usually return after a few seconds , but most web page will not return completely , until you mouse-over all the element . the easiest way to get the screen back be to switch window , and then switch back . this become very irritating after a few time , and you be leave sit wait for it to decide to refresh . I do not know whether there be any way to satisfactorily upgrade you graphic if all you have be a PCI slot , but bite the bullet and get a new pc be preferable to this .
