I am looking forward to buy an Audigy2 ZS sound card . I want to hear your comments especially from those who has this card. Will it make any significant improvement in DVD, music listening and playing games? Currently i am using SB live 5.1 and the DVD and games are pretty good. But i need some more punch and sound clarity . I would buy this card whatever it costs if it is a good performer. Should i buy this card or not ?
