[G4] G4 Processor Upgrades

[Michael L. Brown]

Six months ago, I invested in a  PowerLogix PowerForce47 Dual G4/1.2 
GHz for my G4/400 Gigabit Ethernet. Uses the Motorola/Freescale 7447 
Chip without a L3 Cache. Also required patching the NVRAM. Was 
significantly louder and only marginally faster converting and 
editing audio files than the three year old PFG4-1000 cache card it 
replaced.  The PFG4-1000 used both L2 and L3 cache. Since the whole 
purpose of buying the PF47 dual was it had a more efficient heatsink 
and larger fan on the card, and was supposedly quieter, I was pretty 
disappointed. The large case fan ran a lot faster and more than made 
up the expected difference.

A couple months ago my daughter's iMac 400SE died and and I received 
an unexpected bonus at work, it only took me a day to convince the 
family banker (wife) that I should invest the bonus in a new G5 1.2 
GHz dual and give the G4 to my daughter. Now I can edit music without 
noise-cancelling headphones.

My advice is buy a new G5, if if you don't have any software that 
requires booting for OS9. If you do and it won't run on Classic in OS 
10, then I suggest almost any PowerForce57 which can use both L2 and 
L3 caches over a PowerForce47 which can't.
