Hi guys, please help me.
Im a bit confuse here, i had build a new pc and i have soundcard creative soundblaster audigy value from my old pc, but as i see my new mb have high definition onboard audio realtek alc888 which capable of 192khz, 48hz and my creative sb audigy only support up to 96khz, 44,1hz.

From rough spec i think my onboard audio win and my creative sb audigy value quite an old card.
Which still provide the best sound quality?
