have: powermac g4 quicksilver
1 cpu 933 mhz
L2 cache 256kb
L3 cache 2mb
768 mb memory
133 bus speed
Want: to make system faster for video editing, dvd burning etc
Specifically would like to know if I should buy cpu uprade? or try to fool with settings/overclocking? or maybe an upgrade card?
Any advice would be greatly appreciated as I have only been a mac user for 2 years.
Thank you very much in advance for your input.
