well SiS makes lowend products, usually with a lot of stuff incorporated. All mobo companies used Sis chipsets at one time or another, but it's not for the serious hardware computing person. The solutions it provided were not very solid, and PCChips uses Sis chipsets a lot because it is cheap and have everything onboard like sound lan vid, etc. Dunno how there AMD T-Bird solution is gonna turn out though. From my experiences, it's a slight lower than average company, but things can change quickly in this market.
