Hello Everyone, I have been building computers for quite a while but I have never purchased a high quality sound card for them. I have always used the onboard sound and currently I am using the SupremeFX that came with my Maximus VI Hero MB. I am considering purchasing the Sennheiser PC 363d headphones and I have been reading about the USB sound card that comes with it. My question is this... is the usb sound card that comes with the Sennheiser better than the SupremeFX onboard that I have on the Hero MB? Not much of an audiophile. Please feel free to educate me. Thanks.
