currently using an Asus D2x. i'm really, really happy with that one. had my share of creative cards in the past two decades. actually the asus is only my second card not to be from creative. had a load of driver problems with numerous creative cards. some died, others are still operational somewhere. but, in my opinion, games support the X-fi chips so much better. personally, i think that overall build and sound quality of the D2x is way better than any X-fi based card. got it hooked up (toslink) to an onkyo receiver in combination with canton speakers (just stereo, that's fine for me) - awesome. will probably be one of the few parts in my rig surviving the transition to socket 2011 in Q4 '11 or Q1 '12.
have fun!
