Physical limitation of this graphics card is now fixed, so I see no reason to buy the ATI Radeon HD 5770 Graphics Upgrade Kit for my Mac Pro: Now, the update to Photoshop CS4, under the most recent operating system, allowing rendering Open GL instead of disable. Now I'm in Mac OS 10.6.8 Snow Leopard with Photoshop CS4 (11.0.2) instead of Photoshop CS4 (11.0.0). I turned off the computer and pulled the Radeon X 1900 XT card and re-inserted the OEM Apple nVidia GeForce 7300 GT card. I then manually shut down the computer and doing a manual start so that Snow Leopard would use disk maintenance. This morning the Mac Pro close its dual display, while I was working, and I had to make another cold cut in order to restart. In addition, the computer was material freezes about once a day. Last year, the Radeon X 1900 XT graphics card created scratches on my screen when it is running hot and sometimes dual turns off just as I was working. This card allowed to Photoshop CS4 and Bridge CS4 allow Open GL rendering. So, I bought a refurbished nine Apple Radeon X 1900 XT. When I got the Mac Pro 2007, in 2009, I was running it in Mac OS 10.4.4.11 Tiger and Photoshop CS4 (11.0.0) would turn off the Open GL rendering when it detected the GeForce 7300 GT card stock, which was on the list of unsupported graphics nVidia GPU Adobe. My Mac Pro Radeon X 1900 XT is retired to my yard serious computer in my basement, but that goes back to the OEM Apple nVidia GeForce 7300 GT, brought encouraging results delivered with my Mac Pro. OEM Apple nVidia GeForce 7300 GT is on the list of Adobe to not support GPU for rendering of the Open GL.
