install this card on a old Dell Dimension 2400 . go from use one monitor at 1280x768 to use two , one at 1920x1080 -lrb- dvi -rrb- and the other at 1280x768 -lrb- VGA -rrb- . this card be a good upgrade to older system that already meet you need except that they could use more monitor space . I primarily want to get dual monitor functionality and want my new 27 '' to run at 1920x1080 . this card satisfy both of those need perfectly and have extend the life of my antique dimension 2400 by several year . I be use this for regular application , I can not attest to how game perform . after disable the on-board graphic controller there may also be some performance gain as well , i be not sure yet . keep in mind , this card be for PCI slot , not pci-express , which make it perfect for older system that only have pcus slot . there may be some difficulty with the install . at first , I plug the card in and get a blank screen once Windows start . I then reboot and start in Safe Mode . once in Safe Mode I install the driver from the provide cd . there be a error when install the audio driver from the disc , I be able to afterwards boot regularly however anyway and get full hd video resolution . I then download the latest driver from Nvidia and everything go smoothly from there out . I disable the on-board graphic controller , then plug the 27 '' in via DVI and the 19 '' in via VGA and reboot . after a little configuring in the display property I have everything set up like I want it . to clarify , this card will support 1920x1080 if you monitor support it . the card will support dual monitor functionality - either by use one with the DVI plug -lrb- either straight DVI or DVI to VGA conversion , for which the adapter be provide -rrb- and the other the VGA plug , or by use one of these plug in combination with you on-board graphic controller . one thing that might also be possible be two monitor via this card and a third use the on-board controller . I do not have three monitor so I could not test this . finally , this card be PCI NOT pci-express . this be ideal for everyone who have older machine like mine that have a few upgrade here and there and be perfectly functional but just do not have enough monitor space . bottom line , great card for older pcus slotted system if you want more monitor space .
