I have a dual 450Mhz Sawtooth with a Uni-North Rev. 7 and 1GB RAM.

I am wondering that if I bumped it to 500Mhz or 550, would it matter? Would I see a performance increase?

I want to get all I can out of it, but I am not sure if it would be wise to do it...

I know there are places that tell you how to do this, but has anyone done this with a G4 of this age, and one: have you done it on a Dually, and two: was it stable and was there an increase in performance?
