So I've seen these drop-in processors for G3's and G4's by Sonnet, OWC and some others. But can any one give me some advice on these. I want to drop one in my G4 533 Digital Audio just to get it above 1GH, but it's working so flawlessly I don't want any hiccups, or driver issues. I've spoken with the tech department at Sonnet a bunch of times already, but now I need some real-world advice from some real-world people. Mainly I want to know if these upgrades are even worth it. Any info on this topic would be much appreciated.
