Hi,

Its worth knowing a few more specifics re your iMac G5.

For example if yours is the 20 inch iMAc introduced Aug 2004 and discontinued May 2005, it started with OSX 10.3.5 and is upgradable to OSX 10.5.8. An OS upgrade might make some difference letting you run some more recent software but if you want to do something more memory intensive other than running Office etc you have a maxxheadroom of 2Gb Ram. Thats a finite limitation and if you need to do stuff needing more Ram then you need to explore the upgrade path to an Intel processor.

Hope this helps,
