I have a powermac G4 (AGP Graphics) runnining at 500mhz.

Is it worth it to buy a dual 1ghz or 1.3 ghz processor from here http://eshop.macsales.com/shop/accel...PowerForce-G4/
If i were to do video editing with the computer, among other routine work?

Or would it be a better idea to put the money to into the G4 quick silver and upgrade that or look for one already running dual processors?

I basically don't know what my options are or what the difference is between the G4 Powermac towers so I don't want to put 300-400 into it and it not really be worth it or be a stupid newb mistake.
