i'm looking to get a 5.1 surround sound card for my 5.1 headphone (roccat kave).. i was considering "creative sound blaster x-fi surround 5.1 pro" until i heard some forumer mentioned that it has driver and compatibility problem.. also theres this SC called asus xonar u1? it sounds rather satisfying but i cant seem to find out whether it supports 5.1 surround.. i'm also open for other recommendation though.. please help >.< i hope i'm posting at the right place
