Disable the onboard. Chances are it's slowing your rig down by an aweful lot when you're using it (FF7 world map runs silky smooth on my rig, unless I'm using the built in audio) and a bit when your not.
Besides, the Live! has all the features you're ever going to need AND it's faster, so why bother with the built in? The WSS is not exactly anything you're going to miss (I'm assuming you've got the same c-Media built-in sound my last 2 boards have had).
Just disable it through BIOS, and you've got a bit more speed and a spare IRQ (or two!).
