It depends on your CPU of course, but in general, something like 1-2% or less.
Go back to the days of SB Live! and such though, and you could find that 32 channels with EAX-like effects could reduce fps in a game by about 10% easily. If you were always running a very fast system, or graphical settings that were within "safe limits", you'd probably never notice the games stuttering. If you were somebody who liked to max settings, getting those extra 10% fps, could make a difference.
Today though, the CPU load is so insignificant (and the onboard audio actually do more of the work than things like AC'97 did) that it doesn't really matter.
