We use a FreeBSD system on a HP DL320 with PCI-X and 2onboard gigE
broadcom controllers, 1GB ram (5% used)
We saw a maximum forwarding speed of 912Mbit/s from one nic to the other
(with NAT applied) with a packet size of 1500bytes (max).

The main limitation you'll come across is that of the PCI bus itself
(assuming your GigE interfaces are PCI cards). Even best case scenario
you get one linked to the southbridge, you've still got 2 on the PCI bus
vying for 133MB/sec (estimate 110MB/sec actual throughput).
At full whack, a GigE interface would be 125MB/sec, so it's easy to see
just isn't up to it if you expect those interfaces to be fully loaded
of the time.
You might be better off getting a dual Xeon board and a single Xeon CPU.
suggest something like the NCCH-DL (or PCH-DL if it's still available).
includes the Hance Rapids PCI-X controller so you can put your two other
GigE interfaces onto that rather than the PCI bus. You've still got the
integrated into the southbridge (intel chipset - pretty good
which would give you your 3 interfaces.
I can't comment on the user requirements - I've no experience with
deployments of that size.
Out of curiosity, has anyone actually seen close to 125MB/sec out of a
card? The GigE networks I've used have all peaked out at around
regardless of switches, NICs, etc.
