I install this in a Dell Dimension 3000 , with Intel Pentium 4 -lrb- 2.8 ghz -rrb- with 1.5 gb of RAM , run Windows 7 Professional x86 . the Dell Dimension 3000 only have pcus slot , so I be limit to what I can use , most newer card be pci-express , so find a pcus card , that be any good be tough . I then come to this product . with 512mb of memory and a pcus connection this be a great choice ! I open up the computer and plug this card into a available PCI slot -lrb- the heat sink on the card be large , so you may need to put it away from other card -rrb- , and turn on the computer . straight from boot the computer could use this pcus card and have no problem use VGA . Windows detect it and I install the software -lrb- I do not use the CD , instead I download the latest software from NVIDIA 's website -rrb- . I reboot the computer and be look at great graphic with super fast performance ! I plug in a hdmus cable go to my tv and it switch over with no problem , so now I have Video and Sound go through the HDMI cable from this card !!!! I have test the computer by view video from my tv tuner -lrb- over the Air HD programming -rrb- and have no problem . all the video that would not play before -lrb- like Media Center DVR content play perfectly -rrb- and they be no shutter or video problem ! when I run the Windows experience here be my result : Processor : 3.7 memory : 4.1 graphic : 4.2 gaming graphic : 4.5 -lrb- amazing improvement !!! -rrb- primary hdd : 4.1 the result before the new card be install -lrb- Intel Integrated Graphics -rrb- : Processor : 3.7 memory : 4.1 graphic : 1.9 gaming graphic : 1.0 primary hdd : 4.1 in the end this be a great video card for any computer not just older computer -lrb- although a more powerful one might be need for gaming -rrb- .
