the Phoebus is sweet, but it's not on the list. Might want to check with Asus, but I can't see why I wouldn't work. The phoebus does have a break out device to attach mic and headphones - this will NOT work with Tiamat, you will have to run the headphone's cables to the card's jacks on the back of your case.
Well, I read some that it works well with the Tiamat by plugging the jacks in the sound card itself. So it is not gonna be a problem since I will put the case near the monitor. But thanks for the help though.
You might want to try the Vantec 7.1 solution on that list. I believe that's the only thing on the list that will work with ps3 and xbox 360 through optical in.
