[G4] Upgrade Processor for AGP/400Mhz G4

[Thomas J. Fobia]

Thanks to all for the information about G4 Macs. Now the decision as to 
which OWC processor upgrade is best for my AGP/400Mhz G4. On the one 
hand theres the "PowerLogix PowerForce47 G4/1.6GHz with 512K 1:1 L2 
Cache on Processor for PowerMac G4 AGP Graphics/Sawtooth" at $239. This 
unit apparently varys its processor speed depending on applications in 
use. The detailed data on the unit states that it runs at 900Mhz most of 
the time and only jumps to 1.6 when loading a new page into your 
browser. CPU Director now also supports DFS, or Dynamic Frequency 
Switching. DFS allows the operating system to dynamically choose either 
full or half CPU speed depending on the software load. The user can set 
the parameters for this via the Energy Saver System Preference. Since 
the majority of tasks do not need full throttle CPU power at all times, 
when set for 'Automatic,' the operating system increases clock speed as 
needed, and decreases it as needed, on the fly - all without user 
intervention. Am I paying for 1.6 only to use 900Mhz?

Then theres a "PowerLogix PowerForce55 G4/1.4GHz (1400MHz) Upgrade with 
2MB Cache for PowerMac G4 AGP Models w/100MHz Bus" at $249. The data 
sheet states that it runs at 1.4Mhz. Maybe this is better because its 
runs at a constant 1.4Mhz.

If anyone has any opinions on these two choices, please chime in! Thanks 
for your comments!

Tom
