Quad socket intel boards are highly specialized parts, not just off
the shelf.   The S771 cpus are not quad-socket compatible as far as I
know.

Even for Opteron, where quad-socket is an off the shelf part it is
still much more expensive than dual socket boards.

You could, however, build 4 dual socket systems, connect them up with
some fast network cards (I'm fond of cheap infiniband cards from ebay
for this sort of thing :)) and create some GR blocks that dispatched
processing to other computers.

On this subject:  Are the frames output by USRP2 broadcast or
multicast?   It would be neat to setup a cluster of systems all spying
the same 25mhz of spectrum and doing things with it.
