Upgrading Mac Pro Processor Step by Step

[mikecorp]

Hello Guys. in 2007 I purchased my first ever mac pro 1.1 intel.
2 x 2.0 GHz Dual-core Xeon "Woodcrest
1GB ram (2x512)
GeForce 7300 GT

and right now I'm looking into upgrading processors.

somewhere in the apple discussion I find out that I should look at:
Intel Clovertown Xeon processors. E5345 (2.33 Ghz), E5355 (2.66 Ghz) or X5365(3.0 Ghz). I need a pair.

Those are Quad core processors and are pin for pin compatible with the 2006 Mac Pro 1,1, they say. Bloody hell they are hard to find.

Is there a possibility to install anything else inside???

I have this website with good prices.

I set to search for

Intel
socket 771
Xeon quad, duo

Is there something that would work? What did you people install for CPU??

thanks in advance!
