Hey Folks, I've got an early 2008 MacPro 3.1 Running OS X 10.6.8, My current video card is Radeon HD2600 with 256MB vRAM. I need a video card upgrade to speed up rendering and export in Final Cut Pro X. Recently I've purchased a re-flashed "Club 3-d Radeon 5850" card. Although it works under 10.6.8, Final Cut doesn't seem to benefit from it at all: rendering and export takes the same time or even longer than with my old HD2600 card. My questions are: 1). Is there any known trick / enabler / kext etc. to make Club 3d HD5850 run it's OpenCL features under 10.6.8? 2). Is there a known way to import video drivers and Open GL framework from OS X 10.7.5 into 10.6.8? 3). Could someone please recommend me a card that works well under the 10.6.8 for Final Cut rendering and exporting? Gaming is not important. Note.: I work under 10.6.8 for a reason, please don't waste your time on advising a system upgrade. Best regards!
