I just got UT2003 and had recently put in a SoundBlaster Audigy. Well... I know nothing about sound options, whats the best one to put it on, and what are the differences between them?

I think they are software, hardware, hardware + EAX? Does that make sense? I've heard software was better, but I'd think you'd want to take the stress from the cpu and put it on the sound card right?

thanks
