I'm seriously considering upgrading my eMac G4 to Mac OS X Leopard (it came with Tiger pre-installed). However, since I am super tight on money (someone loaned me a Leopard retail disk to use ), I'm wondering how Leopard performs on 512 MB of DDR-SDRAM? The processor meets the requirements, etc. (it's a 1 GHz G4 eMac from 2004, I copied the Leopard disk to a DMG and plan to do one of those external hard drive install setups I've seen, since I don't have an external DVD drive and the Mac has a CD-ROM drive) Leopard can be supported on my model. But the question is on how it runs if the memory does not exceed, but rather meet, the system requirements (in this case, 512 MB of RAM, which is PC2700 DDR-SDRAM). Can anyone give me any experience/comments on how it would operate?
