Sweet jeebus Orb, covering all the bases here arentcha?
From your posts in like... damn near every other category I assertain you merely want to power a 2.1 system? To be honest, most chipsets (onboard) nowdays will do more than fine on that job. Its only when you want to get into 5.1-7.1 that you need to consider bigger options.
In my opinion, of course.
