Hi, i use iMac11,1 with NV 9600GT, 10.6.8 beta
i used that posted AGPM (with 0622 as my device, you must change that if you have other nvidia) , made an
LegancyAGPM for
(attatched - for 0622 / iMac11,1) /Extra/Extensions , rebuild /EXTRA mkext (by great Kext Wizard) and got AGPM working.
Here the steppings (you can sue any OpenGL Tool like OpenMark other Benches uses GPU like CUDAZ) to see steppings up/down.

You can also use CUDA FPS Check (for putting some OpenGL load on the GPU, shows FPS) if you have Mac OS X CUDA drivers installed.
