Hello all, I have just bought an iMac g3 333mhz with 64mb of ram. (I do plan on upgrading the ram, but not for a few months until I can get the money) Right now, it has OS 8 installed on it, but I also have a retail CD of OS 9. Should I upgrade to OS 9? Will I notice any performance hits? Is there a way to back up my OS 8 partition in case something goes wrong, as I don't have the original install CD for it. Thanks alot!
