Hmm those VIA problems were a long time ago... nowadays VIA chipsets are just fine. I'm running 3 VIA-based systems nowadays and they all work perfect, even the ones with a bug (KT133a and KT266m).
I don't know what's wrong with the NVidia soundstorm. I've used mine for over 2 years and it never lets me down. Soundquality is good, driver support is good, not a single prob there. I think that Soundstorm still beats any other onboard soundcard.
The IDE driver is a nasty thing. But, not installing it keeps the problem away. Same goes for Intel with their IAA (IDE driver): not installing it gives you great performance and no troubles.
SiS doesn't have these problems? Maybe not, but it has problems of it's own. I've had too many bad experiences with this brand. That's not a grudge, that's experience.
You want links? Well google for it and my guess is you will find more than enough. Otherwhise, phone my nephew and ask how happy he is with his SiS 755 based system. Or my friend with his SiS 655 based board.
I have a SiS 650 based system (laptop) and I don't like it. Especially the onboard VGA and sound is absolutely worthless.
Let's not make this a "flame-a-chipset-brand" thread. I guess the topicstarter now knows our opinions on the brands so he can decide for himself (or ask us for more info) what to do.
