Specificically how does SLI work?

[Hardnuta]

I am creating a presentation on how hardware has changed, and i was just thinking how does SLI work on a motherboard, what components does the motherboard need. Except the 2 or more PCI-E Slots.

Cheers,
The More in depth the better.

If you're talking about how hardware has changed, you might want to mention 3dFX's multi-gpu implementation, confusingly also called SLi.

cheers, for the info
