Sound: want serious sound something like Audigy 2 ? NO onboard.
Serious sound is not anything from Creative. Something based on the Envy24 chipset, such as the
M-Audio Revolution 5.1 (or
7.1) will get you much higher quality sound. There is also the
Chaintech AV710 for the budget consumer.
Serious speakers are not computer speakers at all, much less Creative ones... For good speakers, you need to veer away from the stuff made for PCs and get actual stereo speakers (and an amplifier). But that can be pricey... At the least, try to stay away from Creative.
