    G'day and welcome to the forums.

    The CPUs you are after are the 3.2GHz X5482 model. Be aware there is a lot of discussion the upgrade is very limited and many report not worth the money. Different when I upgraded my Mac Pro 1.1 2GHz to Quad Core 2.66Ghz which flew.

    Firstly make sure you are running the 3.1 Mac Pro model as there was a later 5.1 model with a single 2.8GHz CPU. Have a read of this:-

    2008 Mac Pro Dual 3.2GHz Quad-Core CPU Upgrade (Low-Cost/DIY)
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!
