And my advice is to ignore Shocky, because he's wrong. I have tested games around or 10-15fps below 60fps, and this "microstuttering" is not noticeable when comparing to a single card. So, I call bull#$&%.
In fact, when enabling high amounts of AA in games like Oblivion, a single GPU setup actually ruins the experience by dropping into the 20s which is very choppy compared to a two-card setup that cruises along at 40+fps. During these tests there was no "lagging" or "stuttering" at all when ~45fps on the Crossfire setup. But there was tons of it on the single GPU:
