Apple *really* needs nVidia GPU options it seems.
I'm running a Mac Pro 2010 model, with a GTX285, and it runs like a dream, output through my Blackmagic Decklink 3d.
I'm cutting h.264 and XDCAM EX together on a single timeline, without conversion, without hiccups.
I'm cutting a corporate video right now, and using the search function almost anytime to look for a clip, and it's really sweet.
Titles with Tiff's on top of video? NO RENDERING.
