I disagree with both statements based on my own personal experience with these cards. I think sound quality is fine ( I do NOT consider myself an "audiofile"). GPU "processing power" loss will be minimal on his card.
Your opinion means little (sorry to be frank) but any decent sound card's quality will blow away any onboard sound or in this case the HD sound on an ATI card. You don't need to be an audiofile to notice a difference.
After spending over $100 on a top of the line sound card you can bet I sure as heck would be making use of it. I'm sure the OP feels the same.
