Dave, ole bean, there *are* LGA775 Xeon products for sale.

Xeon quad core LGA775 X3220 2.4Ghz
http://processorfinder.intel.com/details.aspx?sSpec=SL9UP

Core2 quad core LGA775 Q6600 2.4GHz
http://processorfinder.intel.com/details.aspx?sSpec=SL9UM

The voltage range in those two specifications, could mean
something, or it could be meaningless. Occasionally, there
are errors and omissions in the processorfinder entries,
and some of them never seem to get fixed. So whether
that difference is significant or not, I can't tell.

In the Newegg customer reviews for items like the X3220,
at least one person reported instability in their build
with a Xeon LGA775 in a desktop board. Whether the
individual tested his RAM, and did all the right things,
is unclear.

I don't think I'd go out of my way to buy a X3220, as
a replacement for a Q6600. Personally, I'd stick with
the desktop part. Especially as the Xeon in the example
above, is only available in B3 stepping. Overclockers
like the G0 stepping a bit better, and the Q6600 is
available in B3 and G0.

Current Xeons, actually, although 99% common to Core 2 Duo\Quad, have
different prefetch logic for cache and cores, as well as a few other
tweaks that are geared for server systems and can actually decrease
performance on desktop machines that do not execute the same tasks a
server would.

It is not usually worth the effort over a Core 2 LGA-775 setup,
although certain users might benefit from it.
