[G4] Which is faster, a dual 450 mHz, or a single 800 Mhz?

[James Asherman]

Smartypants neglected to give an answer to your question in his lecture.

Anyway, The answer is that for single processor duties the 800 will be  
faster.
When using a dual processor enabled program the dual 450's would edge  
it out by a bit.
It depends on what you do.
There is not enough difference to matter.
Recently I replaced a 1.2gigahertz processor with a dual 1 gigahertz  
processor card.
There is a noticeable but still only incremental difference. In your  
case, fairly undetectable difference.
