I buy this to use in conjunction with a Ivy Bridge processor 's integrated graphic so I could run 3 monitor without have to use DisplayPort . it seem that 2 DVI port on a graphic card be rare , this be one of the only one I find . I have 1 monitor run through HDMI off the Ivy Bridge 's graphic , and the other 2 monitor off the 2 DVI port on this card , and after a little tweaking in the bio etc. it work like a charm . I do not use it too heavily , no game or anything , but it be simple and painless and work great , so I be quite happy . the only thing that be not great be the rebate process - I hate these , they try to make it so difficult to get the rebate I guess hope you will give up and not go for it . just make the thing cheaper instead ! but they say my check be come in 6-8 week , so I guess I penetrate the bureaucracy !
