I have the Audigy Gamer and I had no problems with it at all. Besides one problem, if you have XP. The card would make a screeching noise when XP crashed. The current drivers fixed that. What I like the most is the EAX features in games with 5.1 speakers or even headphones! It makes games sound great! Yes, I would say your purchase was worth it. What other card would you buy other then the Live! ? The Live! series is older, but cheaper card. Though, I would keep the Audigy.
Where are you getting complaints? I've seen complaints from the Winamp forums, but that's it.
