I've just bought an Asus motherboard which has on-board sound (SoundMAX ADI
AD1986A). However, I'm scrapping an old PC which has a PCI Creative SB Live
1024 card - would this give a better quality than the on-board sound?
Yes, while a SB 1024 isn't a high end card with all the
bells and whistles of some, it's sound quality is
significantly better than that onboard sound.
There are at least two mitigating factors.
1) Creative drivers tend to be overly complex and poor, and
their cards tend to hog the PCI bus which can cause reduced
bandwidth for the card and/or other PCI devices... sometimes
causing reduced performance of the other PCI device or
interruptions in the sound from the Creative card.
2) Depending on the quality of the sound file and
sensitivity of the amp (or headphones?) coming after the
sound card before the (physical) speaker, any differences
might be masked to the point of being inaudible.
In short, try the card because if it works w/o hitches in
your system then it will sound at least as good and
potentially better.
