I'm experiencing some problems with my Intensity Pro that I think might be due to some incompatibility issue with the ATI Radeon 5770 in my Mac Pro 3.2 ghz (Mid 2012).



With the intensity pro card installed it takes about 5 minutes to boot, and there's nothing showing on the display until the finder appears. However I've found out I can speed it up by unplugging and plugging the MiniDisplayPort to VGA adapter back in. When I do that, I immediately get an image on the display and the computer starts to boot.



With the intensity pro uninstalled the computer boots just fine and there's no problems with the displays.



It's all a bit mysterious and I'm not sure if it's a faulty gpu or some issue with the Intensity Pro.



Has anyone had any similar problems ?




Mac Pro, OS X Mountain Lion (10.8.2)
