Am running Vista x64. The latest drivers appear fine so far.
I was expecting a boost in quality from my AC'97 but this thing is just nuts.
When playing music, the sound is more "Fuller" and more sharp if that makes any sense?
The bass is now more pronnounced, but not in a bad way.
Am off to try some games... EAX style.
Did you have to change anything in the bios so that the x-fi card is used?
or is it just plug play, install drivers, remove old?
Hope you've got a decent sound system...little point get the Pro if you've got crap PC speakers.
