Here are the opengl viewer scores for the two PowerColor AX4890 1GBD5-UH video cards (now overclocked to 1000/1100) currently installed in my 3.2 GHz 8-core Nehalem Mac Pro and running in OSX 10.5.7. The first screen shot is from the first of the two PowerColor cards (In BootCamp, I take advantage of CrossFire). The second shot is from the second of the two PowerColors cards. The third is a screen shoot from a lower resolution opengl test on the second card. The fourth is a screen shoot of opengl testing using Apple Software Render.

Which product number do you have? I 've found good information at Info: Overclocking my ATI card? - Overclock.net - Overclocking.net , RivaTuner , and ATI Graphic card overclocking.....All info you need. - Guru3D.com Forums. Overclocking must be done on the Windows side, unless you can get ATI control panel for OSX. I use ATI control panel and Rivatuner. The last cite, above, has information you should consider.
