Yes, I use B4 myself (killer app) and it'll work with any old soundcard. You buy soundcards like the Audigy for the audio input capability and the drivers. And in case you didn't know: the B4 works best with ASIO drivers which give you a very low latency between when you hit a note on your midi controller and when the actual note plays from the softsynth. I have heard of people using ASIO drivers with their Audigy cards but I don't know much more than that. Lately I've had good success with a beta-version of a generic ASIO driver which will work with any WDM soundcard (http://www.asio2ks.de/). On a studio system I recently designed I chose the M-Audio 1010LT audio interface cards which has very good ASIO support.
