I have a spare computer, its simple with an intel core 2 duo processor, a 600 watt power supply and an MSI mobo with onboard video and sound. I want to hook this system to a 42 inch samsung plasma tv to use as a monitor. The mobo has only one pci-e slot. Could someone suggest a good but not too expensive video card capable of driving the tv/monitor and possibly a good sound card as well? Finally, do you think this idea would work at all?
