Re: sound cards
well, obviously the last one is different than the top two, because it is Live! insted of Audigy, which people say is better, but for basic stuff I don't think there is really any difference in sound quality (and it's cheaper of course) but the top two... should be the same. I don't know. I'd go with the second one that actually says "Sound Blaster" on it... just a guess really.
