Just curious. -doug > Yes, it is possible, but at this time probably not worth it, considering you could probably sell your computer and buy a *new* G4 w/Dual 1.25 GHz processors -- the price difference being the same as a Dual 1.25 GHz processor upgrade, which goes for about $1,000. And along with a faster processor you get faster system bus, faster memory, faster video, faster SuperDrive (or SuperDrive period if you don't already have one). Even the next slowest Dual 1 GHz processor upgrade is still $800, and a single 1.2 GHz processor upgrade wouldn't make all that much difference in speed and that one still costs $600. My suggestion -- wait a year (maybe less) and the upgrade card prices will be a worthy investment. If you want to check out what's available (even if you don't buy from them), check out OWC's website -- click on the "Acceleration" link at the bottom of the home page and make your selection according to CPU model -- it's pretty straightforward. http://macsales.com -or- http://eshop.macsales.com/Accelerators/index.cfm 2 cents. - Mark
