I have a 17” 1.5 GHz PowerBook G4 that has an issue with the graphics card and the TAS chip. I’d like to replace my logic board with a new one, but I noticed that the 17” 1.67 GHz model (low res) has very similar hardware parts. Will it be possible if I can replace my logic board with the 1.67 GHz one and make it fully functional without replacing any other hardware parts?
