Hello, I have my SBLive! with 4.1 speakers, and this Xmas I thought about upgrade it to an Audigy 2 ZS and T7900 (7.1 speakers from Creative). But I have seen that Creative has the Audigy 4 Pro. It's much more expensive than my original idea, but I would need to know if this card is really very different, if it is worth to wait for a non Pro (and so, cheaper) Audigy 4, or if there are few differences between both. I have seen in Creative page, that they explain much more about th eHUB than the card!!! What do you think? Tx!!
