The Studio will run just fine on that setup. I have a maxed out 15" (see sig) running Motion 2, FCP5, and DVDSP 4. Runs great. Motion is the only program you need to worry about. If you run too many effects or particle effects, it will bog down the PB. Pretty much ANY DV camcorder is just fine with the Powerbook. As for gaming, Star Wars: Battlefront, Warcraft III, Command and Conquer, and Knights of the Old Republic play beautifully on my Powerbook...even nicer on my Power Mac, but very smoothly at highest settings on the PB.
