Hi all, I will get a G5 or PB to replace my PC, as a new comer, I do have one conern about the audio quality of either one. Music has been a big part of my life, so how do they compare to say PC audigy sound card? If i remember it right, G5 has "onboard" sound, from a PC's perspective, "onboard" usually means bad. As G5 claims to be the most advanced computer, how can it not have a dedicated sound card? And how is PB's audio quality? of course i am not expecting it to out perform audigy, but as in general is it adequate? thanks all.
