I am a huge linux (Ubuntu) fan, but I had to switch back to Windows 7 for a little bit due to school....In that process I setup a 4 Monitor Setup on my desk...When I load Ubuntu, I can only get two of the monitors recognized, and I believe this is because the computer has two video cards and not just one. When I use eyefinity (or something like that) I can get all four monitors working, but 3d Acceleration is broken.... And I need that for some of my school work.
I am really tired of the issues Windows is bringing me, but the Quad monitor setup is incredibly important to me too. I am willing to buy another video card or two if that is what it takes? Would crossfire help?
