EVGA GTX570 Classified 1280Mb 1081
My System before installing the 570:
GA-EX58-UD4P
i7 920 @4GHz
6GB XMS3
10.7.1
Chimera 1.5.4
Mac Pro 3,1
So, I picked up a GTX570 (linked above) on tuesday and I've been pulling my hair out all week while trying to get it to work.
I was replacing a faulty 6870, so I was able to add the Device ID to NVDAGF100Hal.kext before swapping out the cards, and added GraphicsEnabler=Yes and Graphics Mode to my chameleon.Boot.plist (Actually Chameleon Wizard was awesome for making quick edits).
So, I boot back into the desktop and things look good: The card is recognised properly, I've got full resolution, QE seems to be working fine and a patched GeForceGLDriver.bundle gives me OpenCL. Unfortunately, OpenGL is a no-go.
Cue days of messing around with boot flags and chameleon versions and system identifiers, and more than a few times having to restore Lion due to a messed up install of something-or-other. Thankfully I have a separate drive with a clone of my main install so I can easily get back to a working state.
Always the same result: everything works fine bar OpenGL.
Anyway, I read about some people having luck out-of-box with some of the 10.7.2 seeds, so I figure I'll give it a try.
I'm glad I did
10.7.2 (11C57)
Chimera 1.5.4
iMac 12,2
NVDAGF100Hal.kext edited to include 1081
Graphics Enabler=Yes & Graphics Mode
Boots to a desktop with working QE & OpenGL (woohoo!)
However, Cinebench gives a woeful 10fps
So, I stick this:

in AppleGraphicsPowerManagement.kext under iMac 12,2 and Cinebench is giving a more respectable 41fps
And XBench is happy
If not quite as fast as my old GTX260
And NovaBench isn't too shabby, either
I've still got to do some tweaking to the AGPM, but all-in-all I'm well chuffed
Many thanks for all the great info contained within these threads
