Hell, just pre-ordered, by the time it actually ships, I'll have the time to A. Read reviews and see if the card is worth it and B. Save the money to pay for it. If the card is as good as I hope it will be, then great, I'll have gotten a decent price on a good card, epscially after I sell my Audigy 2 ZS. If the card turns out to be a POS, I'll cancel my order and forget about it!
I believe the one thing that could be the most interesting about this card is the onboard 64MB of RAM. My Z-5500's would love to get a hold of some uncompressed audio samples in 5.1 surround while playing Battlefield 2....or any other game that takes advantage of the onboard memory.
