While it's possible, you would lose the other benefits of the new logic board coming with Stoakley-Seaburg among other things. Best way to spend money on an upgrade is by selling the one you have and buying the next one for about the same difference in money.
I've upgraded my quad 2.66 to a octo 2.66. its helped with my 3D rendering and compressor tremendously and saved me about a $1000
*snip*
Since they are coming out with a new architecture Intel probably will not make too many more advances with the Socket 771 chips currently used though....
I read somewhere that Intel have committed to producing socket 771 compatible versions of at least their next 2 revisions. I anticipate upgrading for a few years to come...
Where can I find the steps on changing the processor?
Self promoting are we?!?!?here is a good thread for 2010 mac pro single cpu the quad 2.8 or the quad 3.2 ca become the hex 3.2 or hex 3.33 or hex 3.46.
