Maybe you could try over on forums.2cpu.com, and see if someone has
a quad 604 they want to get rid of. A quick look around, shows products
which are replacements for commercial server motherboards, and the problem
with grabbing a board like that, is finding documentation for
it.
Look at the size of one of these things.

Something like this Z7S WS from Asus
http://www.newegg.com/Product/Produc...82E16813131272
http://support.asus.com.tw/cpusuppor...model=z7s%20ws
or something like this, although this one is 12"x13"
http://www.intel.com/products/mother...00xs_large.jpg
http://www.newegg.com/Product/Produc...82E16813121330
would allow a pair of more modern processors to be used. You
could start with one quad core processor, then add a second later,
for a total of eight cores. With the Asus one, you might get away
with using a smaller computer case for it.
The fastest processor in the Asus support list, is the E5472 at 3GHz
and FSB1600. The reason for the FSB1600, is so you can use DDR2-800
FBDIMMs for memory. (FSB1600 enables DDR2-800 usage.)
http://www.newegg.com/Product/Produc...7161&Tpk=E5472
The next step up, at 3.2GHz, is this one. QX9775 for LGA771.
But it burns 150W, whereas the other one is more reasonable on power.
http://processorfinder.intel.com/det...px?sSpec=SLANY (QX9775)
http://processorfinder.intel.com/det...px?sSpec=SLANR (E5472)
And the QX9775 costs $1550 each.
http://www.newegg.com/Product/Produc...044&Tpk=qx9775
You may want to see if anyone on 2cpu.com has been trying out
the QX9775 or not.

If you want to shop for Opterons, and see what is on offer, try here.
Socket 1207 is what you'd want.
http://products.amd.com/en-us/OpteronCPUFilter.aspx
There are a few boards here, including some quad socket boards.
http://www.tyan.com/product_board_li...hipsetid=99999
The quad socket uses 8000 series processors, because of the need for more cache
coherent HT interfaces to interconnect them. AMD doesn't use the same
kind of interconnect between processors as Intel does. 8000 series processor
prices will take your breath away, so you pay dearly for an extra coherent
interfaces.
http://www.tyan.com/support_download...px?socketid=16
http://en.wikipedia.org/wiki/Opteron (see "Models")
So a quad board, with four 8360SE quad cores at 2.5GHz each, would set you
back $2190 per processor, or $8760 for four processors. Total 16 cores.
http://www.newegg.com/Product/Produc...82E16819105208 (8360SE Barcelona 2.5GHz)
The same quad core, but with fewer cache coherent HT interfaces, such that
you can only use then to build a dual socket, would be the 2360SE, at $1300 each.
So the "scalability tax" is an extra $900 per processor (for no extra work on
AMD's part). You could use two of these in a dual socket F, for total 8 cores.
http://www.newegg.com/Product/Produc...82E16819105198 (2360SE Barcelona 2.5GHz)
If you bought a quad socket motherboard, you'd need a big case for it.

I'll leave it to you, to find benchmarks. The motherboard and processor reviews on
Newegg are a good source of info, for any serious issues with this stuff.
