What is the best upgradable CPU for my 2006 Mac Pro 1.1 2.0 Dual Core?

Hey folks,


Just wondering if anyone could help me on deciding what CPU I could upgrade my older Mac Pro 1,1 2006 up-to. I have read some people are running 8 core processors on these units, I do not need that sort of power but something a little quicker would be great. Thank you for your help and opinions!


These CPU units are going for a decent price, but I am not sure if they would would be compatible or if there is a even faster CPU I could use:

Thanks for your response and the helpful link Grant.


Were you referring to the Xeon 5355s (2.66Ghz/8MB/1333/Quad-core) when you said it looks to be the fastest you could run in the 2006 series of the Mac Pro? Just want to weigh all my options before upgrading.


Also do you have any recommended sites for help on manually changing the firmware?


Thanks again for all the responses.
