i have a powermac g4 and i am looking for a proccesor upgrade. so is a dual 450 mhz better or a single 733?

Question

processor help!

Answer 1

A single 733. A dual 450 does not mean 450x2, or 900. It means they work in tandom at 450 mHz. I personaly have a G4 silverback with a 733 with 1gig of ram running OS 10.4. It gives my PC with a 2gHz processor and a gig or ram a run for its money. It never bogs down when I use it!
Go for the 733!

Answer 2

I guess it depends on what you want to do. My computer I just built, I went with a AMD 64 single core. It plenty fast for what I do.
The link may help you, I just browsed over it quick, but, it help explain.
