Hi, I was just hoping for some input on which is the best upgrade option for my begie G3/458mhz..Will I see a serious speed boost in OS X by swapping to a 500mhz G4? What about the recently released (or soon 2 be) Powerlogix 800mhz G3? Anyone who has gone this route could you please give me some info, as the local seen is all about the new G4's (which i can't afford..YET!) sooon i hope!) Thanks for any input you can through at me!
