Hi,
In case you find it helpful, used 4 slots, same monitor, single gtx 295 card.
Limiting diablo3 max foreground to 60fps on all slots, remove all details, set low fx, etc, CPU strategy not round robin (that worked worse), used the all for all (not sure what it's called right now), with 60fps/20fps, everything worked fine (30-50fps on active slot, actually playable). Finished the beta with 4 same chars (first wd, then barbs and monk), then with a mixed team (wiz, dh, barb and monk).
It's a 2 and a half years old computer and I was frankly impressed with how responsive slot swapping was and how well everything worked together.
On my first try, I limited diablo 3 max foreground to 15fps on secondary slots and that generated a problem like the one you're describing. Moving the mouse on the main slot generated bigger moves on the secondary slots.
