I have 2005 Model G5 and would like to upgrade to a newer OS so i can install Windows7 is this possible Please Help.
You are already using the latest OS X version that will run on your G5.
Not possible. 10.5.8 is as far as you can go.
If this machine is so powerfull and have Dual Core 2GHz why can i up grade, i haved done this to a PC and it works sorry this is my first Mac,
The machine's relative power and the number of CPUs or "cores" is not relevant. Snow Leopard requires an Intel CPU such as the PCs you may have been using.
Mac OS X 10.5.8 is the latest available for the PowerPC and you already have it.
