I do pro audio for a living and using an Audigy 2 card (platnium) for the past 2 months. Prior to that I was using a 5.1 live. For my ears, I could hear a huge differance, of course thats what I do for a living. I have to hear the slightest changes in sound. I've read up on Soundstorm, but honestly I'm not impressed. Its decent, but it has a long way to go. From what I can tell, its just as a good as a 5.1. I've been using creative products for the most part and haven't had any problems. I did get a soundcard a few years ago (I think it has the aureal2 chipset) and was very disappointed. I know some people have problems with their cards, but so do people with their video cards . Its normal. If you really want a good card, get a Gina soundcard. But even then, the Audigy 2 is catching up. I have noticed quite a few software companies (audio software) are still recommending the soundblaster live 5.1 for use with their software. My 2 cents. Hope that helps.
