I have an old soundblaster live value. This is the one without 5.1. I want to know if I would really see a difference upgrading to the audigy. Also, I have klipsch 4.1 speakers. I like to watch dvds on my computer too. I just want t to know the differences you guys see. Does this mean I would have real sourround sound with this card? I know I do not have a center channel but I have the rest. Thanks!
