How much difference will i notice between the two. I listen to music on my computer almost 2 hours a day. And rarly use headphones on it. I want to know how much difference will there be between the 2 cards. I like a lot of bass and im not to much of a freak about how clear it is. But i still want it to be clear and undistordid. all comments are helpful . thanks I will be using a logitech z-5500 system with the sound card. Matt
