i have a b&w g3 400 that i installed the powerligix g4zif 550 in. it has made a HUGE difference in the OS and overall speed. i also threw in an ati 7000, once again, BIG difference.. primarily on os X. the reason i went with the powerlogix versus the sonnetwas the fact that you don't need an enabler for osX, to make the processor function. in os 9 you do for both. sadly, the 550 isn't made anymore. you MIGHT look at the g3/800 upgrade, with full speed backside cache, as a bigger boost, if you don't use a lot of altivec applications. -----Original Message----- From: Thomas J.

Sonnet makes a 500mhz upgrade ZIF Encore. Is it worth upgrading? Is it worth upgrading the Video card to a Mac Radeon 7000 also?
