well I won't claim to be a sound guru. As far as I am concerned anything more than onboard sounds is a waste of money that could be spent on a faster proc or gpu.
but from looking around then net a bit it sounds that the newer titanium card is better
"In our tests, the biggest thing that stuck out to our ears was that the
audio coming from the newer X-Fi model was noticeably 'crisper' and
'richer' than even the older X-Fi. Additionally, the 5.1 channel
separation was MUCH more defined and immersive. We can't wait to try it
out on a 7.1 channel system as soon as possible.
With
that and the additional features that EAX, the Crystalizer, and the
inclusion of Dolby Digital Live provide, it is hard not to recommend
this card to gamers looking for the most immersive audio experience
possible. "
