How will the impending release of the 970 and a 64bit version of OS X affect current Mac software, specifically "Pro" apps such as Final Cut Pro? Will Final Cut Pro run as well (i.e. quickly) under the 970? Do applications, or just the OS need to be coded for a specific processor? Suposedly, FCP has been optimised for use with the G4. I don't know anything about coding software, but intuitively, it would seem that a minor software update (a .x release) wouldn't be enough to allow an app to take full advantage of a 64bit OS, let alone a 64bit processor. With that in mind, is Apple going to release 64bit versions of it's Pro apps, sometime after releasing the upcoming versions? Will I need to upgrade to FCP 5, within 12 months of the FCP 4 June release? And of so, will it be worth it? Will performance increases be that significant?
