Hey, you use AMD catalyst control center. Make sure you have a the bridge fully seated.
Then go into the software and enable crossfire under the advanced options.
As for three monitors enable eyefinity. It only requires one card but is far better with 2.
Once three of the same resolution monitors are detected the eyefinity tab will appear.
If you have a card like mine you may have 2 dvi 1 hdmi and 1 display port. In this case you will
need to purchase a Active Display Port Adapter. It should only cost $25, my favorite it the XFX adapter which you can buy on eBay and Newegg.
From here just create a display group, arrange, adjust Bezel comp, and your done.
Hope I could help :-)

It works fine without the bridge, as the bridge is anyway relatively low bandwidth thing. The bridge basically a modified DVI interface and thus can only do up to 2560x1600 resolution - it's used to send rendered frames to the "master" card if available, if not available the frames go over the PCI-E interface which has a lot higher bandwidth.

As long as your PCE-e is not overloaded (and I dont see how it could be with 6770 cards even if it's running on x8 mode) then the performance is exactly the same as with the bridge.

This is especially apparent if running Eyefinity as the bridge cant take the Eyefinity resolutions but the stuff is working just fine as anything not fitting in the bridge will get delivered over the pci-e.
