Exhaustive list. I had my share of Cisco config as well a few years back, ethereal is your best friend.
Since you'll be gaming, no sense in getting the one with the built-in video, since you'll be buying a more powerful card anyway. Be aware that the realtec 883 codec on both boards sucks big time. On a basic, cheap, 2 speaker stereo setup it may sound ok, but if you try to use a quality 5.1 or above speaker system you'll notice lots of background noise and hissing. The HD codecs are passable, but the ones they call "High Quality", basically a marketing stunt to trick you into thinking it's HD, are really bad.
Other than that, I dont see any major reason to go with one over the other. I assume the main reason you're going AMD is to make a cheaper system (with a 100$ single-core athlon) ? Otherwise there's better value on the market right now.
