I have a Soundblaster Live card and the Audiophile residing on this computer. I went to the Audiophile because of it's specs vs the SB Live and the lower noise floor. It definitely made a difference.

I'm not up to snuff on the newer Audigy card specs, but the only reason I still have the SB Live is because I like to work with soundfonts on occasion. Other than that the Audiophile does everything I need and I get good clean recordings with it.
