Wanting to confirm the Sapphire 7850 working (http://www.newegg.com/Product/Product.aspx?Item=N82E16814202004). I had to appended to the Info.plist inside AMDRadeonAccelerator.kext & ATI7000Controller.kext the value 0x68191002 wherever I found 0x68181002. It was 2 places tops, one inside each Info.plist. I flushed the cache, and rebooted.
When that was done, my monitor had both the IGP and 7850 plugged in. The 7850 was in via hdmi, and the IGP used dvi. The startup does get the white flickering screen. Rather than sleep, I put a password on my login ('password' . That way, when I start to get the flickering white snow, I jst enter password, hit enter, and wait for my monitor to detect hdmi. Works a treat (no need for sleep)
Also, you have to remember to un-mirror the displays, if you have both hdmi and dvi plugged into the same monitor. Otherwise, the fps will drop down to the lowest common denominator. In this case, the i4000 IGP on the Z77MA-G45 motherboard. If you don't do this, heaven engine will give you around 6fps. Un-mirroring and setting the primary display to the hdmi connection, I get around 45fps.
You can either disconnect the dvi at this point (thus leaving osx with only hdmi in) or you can hit source to jump between the two (which is slightly strange but, whatever).
