I got one and have it hooked up to my hi fi, for games in XP it's a good choice if you have vista everyone said go for the Xonar when i asked which card was best
I went with XP in the end, and for XP and gaming the X fi probably has the edge due to the fact it's heavily supported by most games
In vista a lot of people said they had trouble with the drivers, and that the Xonar was the superior choice
