My facts, are based on personal experience and convos with engineers at Apple. I'm glad the combo is working for you. I also use the gt120 for gui one of our boxes, but we've stopped using said box for FCP. It just wouldn't play through a sequence.

I wonder, do you do tape mastering from FCP? Do you have dropped frame warning on playback enabled?

I've seen it first hand where an fcp install on a box with gt120 gui wouldn't playback without dropping frames, switched out gpu, 0 dropped frames.

I'm well aware FCP doesn't use GPU computational acceleration. But it does use openGL and the graphics buffer to draw the frame on your screen, which is why fcp requires Quartz Extreme. So there is a reason for it. I'm sure a software fix could be implemented, but I wouldn't hold my breath for one, considering the card's age.

BTW, it's not just me:

And of course there are plenty of people who can't figure out why their system is dropping frames, all of whom have the gt120, here is one such case. But these pop up all the time in the FCP forum.
