    i have two questions. Current i use a Mac Pro 1.1 with 2x 2,66Ghz Dual Core Intel Xeon. I plan to upgrade it. In an other threat i've read that the best upgrade Option is an XEON 5365. But will this CPU work out of the box or do i need to change some Software? Is there anything i need to consider?

    Will this Modell work? :


    My second question is: Will an ATI Radeon 5770 Graphic Card designed for PC work out of the box or do i need to flash something?

    Thank you so much for an answer and sorry for my bad english!

    Best Regards Jonathan

    Yes, that cpu will work. You need a matched pair though. the cpu's will work but will not be reported correctly in system profiler until you flash the efi to 2,1.
    My pc 7950 worked out of box, I flashed it for boot screens.
