I have owned an 08 MacPro since it release, but I recently picked up another for my home office. I run a video/photo company on the side and wanted to be able to edit on the weekends without having to go into the office. The home machine is an 08 MacPro, dual 3.0ghz quad core processors, 32GB ram, 2 x OCZ Vertex 2 SSD's in RAID 0 for the boot, 3 x 7200rpm 1TB drives in RAID 0 for scratch / media disk. I added two Sapphire 7950's after I purchased this MacPro. My problem is that FCP X performance is TERRIBLE. I am running 10.8.4 12E55 and FCP X 10.0.8. I see a combined max of 5fps in Neat Video, where as Windows users are seeing nearly 10-12fps PER GPU. I realize the 7950 drivers a currently complete crap, but is there anything else I can do to eek performance out of this box without spending money? Since the cards have an EFI/BIOS selector switch, and I don't use Windows, I wondered if it would be possible to flash an overclocked EFI to the alternate selection position. Would I retain boot screen? Has anyone even though of or tried this yet? Can anything at all be done to boost RAM or CPU performance? I am not faint of heart and have been tinkering with (breaking) computers my whole life. I need to be able to edit and render videos at an acceptable rate, but running out and buying a new machine isnt an option. Any boost in performance from any area of the machine would be welcomed. (Please let me know if I left out necessary information) UPDATE: For anyone new to this thread - the problem is not raw hardware but instead optimization. A thread on Netkas exists to track the issue as it has been flushed out.
