"Only driver can find for this sound card!"
It is a really good Driver, gets rid of the terrible static and works with all my computers. It has very high quality sound and lets you choose what devices (external speakers for instance) you want to play and what not to. Works on XP + other OS's.
The sound (when not disabled in control panel) takes a little more than a MB of RAM and the installer is not very specific.
An awesome sound card and I think it was a great upgrade from my old crappy one! Also the only Driver I could find on the web! :D
