I don't know about the exact sound solution used in ECS K7S5A but remember that almost all cheap sound cards these days use the same chip/codec as those used onboard the newer mainboards (e.g. CMedia or Fortemedia chips/codecs). This means that you probably won't get anything new from buying very cheap cards.

For under $50, Hercules Fortissimo III is very good value with good quality sound and it performs well in games. Creative's Audigy (around $65) is another option that may do a bit better in newer games and is a very good sounding card for the price.

I was using onboard sound. I just upgraded to the Hercules Fortissimo III. It sounds great. I bought it online from NewEgg for $48 dollars (including shipping). There are certainly cheaper cards on the market, but this seems well worth the price.

It did take some tuning to get it to work though. I have a VIA chipset and had to download the latest drivers to make it work. In all fairness downloading the latest drivers was probably something that I should have done anyway.
