Can a rig with an amd a series CPU mine with the onboard graphics?

I mean in addition to the mining done on the discrete gpus.

Would it be enough to make the a series CPUs worth the extra $ over a sempron?

It would make such a small difference it wouldn't be more than a few percent, while increasing your power usage by more than that.
