Actually, for the most part these Q's won't even apply to me. Mostly I'm just curious. 1. When using FCP/Color, which GPU will it use for rendering? Can you set which one? Will the app windows have to be on the same screen as that card? (Forgive me any noobism here, I've never used FC or its bundled apps.) 2. People figured out that you can run Tiger on a 2008 MP when using the 2600...but what happens if you have both a 2600 and an 8800? Does it work at all? I presume the 8800 won't be functional, but how will it behave - eg. will its fan run normally or at full speed? 3. I think I might have seen the answer to this one in another thread, but it escapes me now - how does an 8800+2600 setup run in BootCamp with the various versions of Windows? That's all I can think of...feel free to add your own queries.
