PUB!
Today I've got a new workstation, I wanted to use a radeon 5770 (on which I will connect 3 screens) and add an 5850 to mine ...

Something very strange happen here ...  impossible to see 2 gpu on this computer.  I struggled a lot then saw something very bad ...  When I install the catalyst driver, I can see 2 GPU, but when I setup my screens with catalyst control center, the second gpu disapear ... 

This is confirmed by fglrxinfo at first, I see 2 gpu, after I see 1 gpu but 3 screens, as if it was impossible to get both working....

I'm on the case, if somebody has some suggestions, I would like to hear them! Edit : Thinking about the dummy plugs needed for windows, I added a 4th screen (yes I could plug 1 of my 3 screen) on the the second card. Then I configured catalyst control center (CCC) to enable this display. YES! I can see the 2nd GPU !!! Enabled Xinerama (remember, this is a workstation) ... lose the GPU... So I understood that the driver is crappy and won't let me doing what I want so ... I will plug this card on another rig. I purchased a 2 pcie-16x slots mainboard for that usage ... too bad, my home office will be less hot this summer !
