Hi guys, I have a G4 MDD Dual 867 that desperately needs a boost. Anybody had good luck with a processor upgrade on one of these? I own a full scale recording studio and this is my primary machine. I can't afford to make the leap to a G5 but I am trying to upgrade my recordings to high definition 192kHz sampling rate. A faster machine is a must. Any help is appreciated.
