I have a low profile Dell optiplex which I want to use as a media center. I am connecting it to a led tv and 5.1 surround sound receiver. I'm looking for a video card which I can transmit hd video and 5.1 audio for a low price. The problem is that this computer only has a pci slot. So I guess I'm looking for a low profile pci video card which transmit both sound and video. Any recommendations would be appreciated.
