I buy this card so I could connect a third monitor to my pc and it have only a single spare PCI slot if you have extra pci-e slot then buy a card for those as these pcus card be far more slower and they do not keep up with the speed of the other card when use as a extended monitor and when you be move stuff between they . for example play a video on the monitor connect to this card slow the browser movement and other screen refresh on the main screen and I guess that be expect . for a card which allow a third monitor to be connect to browse or checkout pdf 's this be great . if you want to play the xplane or similar game to get a cockpit feel with three monitor this be not the right card for the job .
