Could some expert (or pseudo-expert) please explain to me which is better? NVIDIA GeForce FX Go5200 ATI Radeon 9200 I've read in a bunch of these forums that the brand new PB 12" (with the 5200) sucks because of it. So does the Radeon 9200 suck as well, because it's not in the Pro model, but in all iBook G4's? What's the major advantages of one over the other (if any?). I'm clueless on this. Thanks all!
