    Yes. Any X5365 will work, because there was only one stepping ;)

    CPU Upgrade Question for Mac Pro 1.1

    Whilst this thread is now six months old, does the suitability of X5365 3GHz processors, socket 771 change subject to brand of computer as see them for HP, Dell etc as well as the Mac Pro?
