As someone who wouldn't know a Front-Side Bus if it leapt from inside his Mac and danced around the room, I'd like to know if its inferior speed in the G4 Powerbook line is really that big a deal. The most intense game I play is The Sims, so I'm not concerned with massive gaming/FPS performance. On the other hand, I spend 95% of my time in Photoshop and Macromedia Studio. Is this FSB thing going to noticeably impact my workflow? Although I like the idea of mobility, I don't absolutely need it, and if this FSB thing is going to make my PB look like a hobbling gimp compared to the inevitable PBG5, I'll get a WWDC Powermac and wait. Thank you, in advance, for the technical lowdown.
