Re: recording ?
right you will need a soundcard designed for recording rather than a typical gaming card like the Soundblaster. I would take a look at the m-audio soundcards like the delta 44. This will give 1/4" connections from your computer into your mixer, DIbox or whatever you use. I have the Audiophile 2496 wich is a similar card with different connections and I run the Rca's right into my mixer and it works quite well for me.
