The X-fi cards are not working all that well even with the recent release
of
their new Vista Application CD, DD/DTS is no longer supported at driver
level
for example, also, there are some serious volume and output issues that
still
need addressing. The support at Crteative Labs is non-existent. Whole lot
of
money for a card that performs miserably. You are much better off either
waiting until these issues are solved, or getting a motherboard that has
good
onboard sound as you wont tell the difference. The cards are certainly not
worth the purchase for Vista.
