I have a pair of Sapphire 4870's on a MSI Eclipse M/B. I'd like to engage the crossfire feature. The boards each have two crossfire connectors and I have two bridges. The part that I don't know is --- One bridge or two?
You only need one bridge per pair. Cards that have more than one bridge connectors are made to support 3-way and 4-way CrossFireX, where the second connector ties the bottom card to the center card.
