Now, lets assume that I had a rig with that could put out 5.1 surround sound via 6 analog ports. Lets also assume that I could pass the audio through a video card via hdmi to a receiver. Now, would there be a large difference between the two? Or does it just matter on how well the cabling is insulated against crosstalk/noise?

Digital signal is a better (clearer) signal than an analog. Then we could dispute if the average user could hear the difference.
