Hi. To my surprise, I've just found out that there are dedicated sound cards, just like dedicated video card. Not many people seem to buy them though. Is there any noticeable improvement in audio quality getting a dedicated sound card? All I can tell is that they offer more features such as 7.1 surround, etc... Which is pretty useless for an ordinary guy like me. However if a dedicated sound card has a better amp, I may consider getting one. I am by no means an audiophile, but nonetheless enjoy listening to clean (as in "less distorted") music. I don't care much about the output power as I only listen to headphones. Is it worth spending cash for a decent dedicated sound card? Thanks.
