I have a (somewhat) older Gateway model SX2802 slim design (small form factor) desktop that came stocked with Intel's integrated GMA X4500 graphics solution video card. There is only one VGA output and I want to "upgrade" to dual monitors. I have one PCI 16 expansion slot and only 220 watt Liteon power supply and thinking of a new video card? I do not do much gaming, but do watch video...any recommendations for a "good" low power video card that can fit in small form factor computer case? Or is there another way to have dual monitor?
