Final Cut Studio 2 on Powerbook G4 1 Ghz

[hallosteff]

I just purchased Final Cut Studio 2, upgraded my RAM to 2GB and now that I am ready to install... I find that I need a 1.25 GHz minimum. Could you explain what will happen if I do install the software on my 1 GHz machine (Powerbook G4) anyway?
Thank you so much,
Stefanie
