Upgrading Mac Pro (1st Gen)

[Defiance]

Just wanted to know, did anyone do a CPU swap on their mac pro dual 2.0/2.66 or quad 3.0 yet? I was wondering i wanted to upgrade the CPU to the quad 3.0Ghz but i dunno which one i shout get the 80w or 120w version? Some guy did it and he upgraded his dual cores to quad but NEVEr posted which kind of LGA 771 CPU voltage he used? Im thinking of just getting the 80w version to be safe but don't want to make it a $1800 mistake?

Any ideas...

I'd be quite interested in this also. I'm running a 1st Gen Mac Pro (2 x Dual-Core 3.0GHz Xeon), and I'd love to swap the Dual-core Xeons for 3.0GHz Quad-core versions, but Intel's model numbering is very confusing, so if anyone knows which Quad-core processors are compatible with the 1st Gen Mac Pro, I'd love to hear from you.

Edit : Found this article by AnandTech which seems to answer my questions

There exists an 80W version of the 3Ghz Clovertowns?

All I see is the 120W X5365 model, sold on Newegg for $1200 each.

Wikipedia http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Clovertown.22_.2865_nm.29 makes reference to a 150W version as well, but no 80W.

At $2400, it makes little sense to upgrade your 2006 Mac Pro. Unless you can score a pair on the cheap from Ebay, that $2400 is much better spent towards a Nehalem Mac Pro next year, or a Sandy Bridge model in 2010.
