the onboard graphic card on my old Dell Dimension e521 have only a VGA graphic port . when I decide to set up dual display -lrb- a monitor and a projector -rrb- , I go with this graphic card , which will support dual -lrb- possibly three monitor -rrb- monitor . its low price -lrb- 35 when I buy it -rrb- and the positive review be what clinch it for I . the installation of the card be easy . I simply insert it in the PCI slot of the computer , hook up the cable , fire up the computer , install the driver on the CD -- and it be work . I be also pleasantly surprise that it improve performance on my Photoshop CS5 very noticeably . dual Monitor support -------------------- this card have 3 graphic port : hdmus , DVI , and VGA . so , you could conceivably set up 3 monitor with it . I use the DVI connection for my monitor and the VGA on my projector -lrb- which have neither DVI or HDMI connector -rrb- . with the VGA connection I do run into a problem with `` ghost '' on my projector display . as a workaround , I run a hdmus cable from the HDMI port to a `` hdmus to VGA Converter , '' and a VGA cable from the `` hdmus to VGA Converter '' to my projector -- this setup solve the ghost problem ! improve Graphics Performance ----------------------------- one app that I use very often be Photoshop -lrb- cs5 -rrb- . however , it be always be very sluggish on my computer . one particular problem that irk I be I when I press and hold down the space bar to temporarily use the hand tool , the image would not pan or if it do , it be choppy and excruciatingly slow . after I install this graphic card , the problem be go . Photoshop be now very responsive and much faster than before . -- if you want to set up dual monitor or if you have a onboard graphic card and want improved graphic performance , the ASUS GeForce 8400GS card be a good bet . be aware of the potential VGA ghost problem with dual Monitor setup however . apart from the VGA ghost problem -lrb- which I find a workaround for -rrb- , I be immensely please with this graphic card .
