Edit:
The problem for me with anything before 2.2.0 beta6 was, I could not control my second card without a bridge and 11.8 driver.
Unwinder just came out with MSI Afterburner 2.2.0 beta 7 in which now includes a ton of updates and not just a ton of updates but
• Improved Catalyst version detection for AMD graphics cards unattached to Windows desktop
New MSI Afterburner found here MSI Afterburner 2.2.0 Beta 7 (2011-09-06)
I never caught the "edit" before!
Does this mean, that I don't have to have each card as an "Extended desktop"? So, no more programs opening up on other desktops which have no monitors connected?
If this is the case, I just might have to update mine!
I've been slippin' lately on my software updates!
Would be kinda nice if the boards showed an edit time, I edited it around I think 2 hours after words of posting.
I have not seen any happenings like that at all with drivers 11.8. As 11.6, 11.7 and up, dummy plugs are not required for if you didn't know.
As of the moment, I am using 11.8, and trixx because it is cooler out, I can overvolt one of my cards, MSIAfterburner cannot overvolt any of my cards.
Unwinder just released 2.2.0 Beta 8 few days ago. For your info and for others info.

For 11.6 and up, you don't have to do anything, install any of 11.6 and up, pull off your dummy plug or monitor, drivers will do the rest and I didn't have to have mine extended. It just sits as disabled card but is still read by guiminer if i recall correctly, been a while since I took a look at hardware info under CCC.
Also, you can have xfire bridge on two cards if you like. Enable/disable crossfire in CCC as that is what I do from time to time to do a little gaming, instead of taking the bridge off and putting it back on, I just leave it on and have crossfire disabled while mining and enabled when I game etc.
