Of course ATI says they won't have micro stuttering when their high end depends on the uptake of on Crossfire.

The microstuttering is from the present intervals of the driver, not the hardware.

GPUs get frames in batches, so 2 frames are sent simultaneously to 2 gpus to process, then they finish at almost the same time and have to decide when to present, rather than just presenting as soon as they have the frame as a single gpu does.
