I am going under the assumption that you want an 'eyefinity' set up.

You MUST use an active DP to DVI adapter unless at least one of your monitors has a native DP port.

Your setup is going to be a little funky because you have to use all three ports on the main card DP/DVI/HDMI. The HDMI output has overscan/underscan that you will have to tweak in CCC.



Those cards will triple crossfire according to the Sapphire site.

Doesn't matter, still need Eyefinity enabled AFAIK, even if you don't use all three screens to game.

Not necessarily so. Windows 7 has the ability to run three monitors in extended desktop windowed mode so when you maximize a window it only fills up the one screen.

That being said. I do believe for crossfire to work you need to run all monitors of the primary card.

That's because you need to connect your monitors through the same card.

And it won't work without an active DP to DVI converter.
