But for a price, of course. But if you happen to own an original Bondi Blue iMac, which shipped with a G3 233MHz processor, I can honestly say either of these upgrade cards are more than worthwhile, as is true for any 266MHz iMac owners. These cards are not so much an upgrade card, but a replacement card. You machine is not really changed at all, other than a new processor daughter-card. The only thing you will notice different is the speed.
Speed is always the forefront of a computer buying experience.
When someone mentions their computer is too old and obsolete, they are really saying the machine is simply not fast enough to adequately run the latest and greatest software or operating system. And while no one can say for sure if a 233MHz iMac can run OS X well or not, you can be sure a 433MHz G4 iMac is. No one likes to take their computer apart besides computer-nuts. There are small, sharp little metal things that love nothing better than to peel the skin of your knuckles. They are wires you have to remember to reconnect.
