We are thinking of using a 1.6GHz Intel Atom processor based PC with multiple

We will be doing
nothing else on this PC, just capturing data. So it will host ubuntu and
gnuradio. Does anyone have
any idea if there is a throughput limit that we might be up against, say for 2
USRP2s, say 4 USRP2s.
I'd guess you'll first run into disk throughput issues. If you solve those,
there still might not be enough overall system (CPU, chipset, memory, I/O)
throughput. I don't have any intuition for what the limits might be. How long
is your sampling run? Will all the data fit in RAM?
