What can I say except that I am fully satisfied. I had a Creative Fatality pro standard PCI. I am on windows 7 64 bit and my drivers they disabled permanently. I mainly use with PC150 headset Seinnheiser and 2.1 system Altec Lansing old but correct invoice. And since I have this new card I do not have any driver problem. They immediately installed without any hack. They work perfectly and offer me very rich possibilities and high quality. I have greatly improved in quality HiFi for my music. For games it is relatively close to my old card. Finally it should be noted that there is a Molex connector> 4-pin power into electricity card. Congratulations ASUS.
