I'm currently reading my Asrock Extreme4 z66 motherboard manual and on page 28 for Crossfire, it shows two AMD 5770 Radeons in Crossfire with one Crossfire Bridge and TWO AMD 5770 Radeons in Crossfire with TWO Crossfire Bridge ...

Does adding the second Crossfire Bridge do anything?

I know it's for trifire, but for trifire you need three cards. I was just wondering if having two Crossfire bridges with only two cards does anything (like a performance difference), though I think not ...
