yes. but isn't it better to get soundcard that can decode DTS/Dolby stream??
as anarchy0x said that he has to buy soundcard+speakers, it's better to get a dolby/DTS setup as there isn't much difference in price and have theatrical experience.
even if soundcard doesn't have options for dolby prologic or other surround effects u always have option of using powerdvd encoders/decoders to get desired surround effect..& anyways most importantly creative soundcards sound better with their effects being turned off...
secondly buying xifi xtreme audio is like "bashing ur own head with a damn sledgehammer"..
guys xifi xtreme audio is nothing but a rebadged audigy value/SE with xifi drivers..& IS NOT WORTH A SINGLE PENNY over audigy value/live 24bit...heck modded xifi xtreme audio drivers work very nicely with live 24bit/value/SE...
basically by hardware xifi xtreme audio is a audigy value/SE PCB with same layout with changed DAC from wolfson WM8768GEDS in audigy value to cirrus logic CS4382 in xifi xtreme audio..
live24bit/audigy value/xifi xtreme audio are based on similar P17 design...there is no virtual improvement in sound quality for that money in xifi xtreme audio over live24bit/value/SE....& hence xifi xtreme audio is a P.O.S
