Hi,
after many hour testing HD 7970 i have new info.
Testing software (All SW was updated on last versions)
////////////////////////////////////////Master Collection CS6 ////////////////////////////////////////
Photoshop - Some problems in OpenGl
in verison 13.0.4 in 13.0.3 no problems. I downgraded on 13.0.3
AfterEffects - No problems, faster than 660Ti
Dreamweaver - No problem
Indesign - No problem
Flash - No problem
//////////////////Final Cut Pro X, Motion, Compressor and Aperture.//////////////////
FCPX - Faaaaaaster
but still OpenGL error in console, OpenCl no problem! But no freezes or app crash if rendering.
Motion - Same as fcpx
Compressor and Aperture - No problems. All Ok.
//////////////////Mac OS 10.8.3//////////////////
Random Freezes Spinning Beach ball or complete Freeze! But no Kernel Panics! I delete kext from System/Library/Extensions/ AppleGraphicsPowerManagement.kext
And now is all ok. I don't know what is the problem in the kext. Same problem was with GTX 260, GTX660Ti and now with HD 7970.
Snow leopard and Lion 10.7.5 has not problem with this kext! But ML is very problematic. Update 10.8.3 still no changes in OpenGL framebuffer errors. Many users have same problem with FCPX on mac (not hackintosh) but Apple is BLIND????
Sorry for my English grammar is not the best. But perhaps you will understand.
