I'm getting a DFI motherboard and I want to know wether to throw down on a flashy sound card or to just stick with onboard audio. I will deffinatly be using this for gaming and movies, and hoking it up to a decent sound system, but nothing more then media really, I won't need any audio input features all I want is decent surround for music.movies.games. Is there a huge jump in quality with the audigy or should I be ok?
