since am getting really kick as$ speakers, i was wondering should the sound card be Upgraded as well. right now i have the Sound Blaster Audigy Gamer, and am looking into the Sound Blaster Audigy2 ZS Gamer or the plain Sound Blaster Audigy2 ZS (between those two, is the there any real big diff besides what comes with the card?) should i stay with my card, or will either of the ZSz make a big diff in quality?
