You might get enough of a bump from something like an HP DL380p gen8
to saturate your gig-e. I wouldn't bank on stably going any higher
than that. And as someone else mentioned, definitely lose conntrack
and stateful firewalling. If you need 'em, move 'em to interior boxes
that aren't dealing with your main Internet pipe.
If you're up for a challenge there are specialty NIC cards like the
Endace DAG. They're usually used for packet capture but in principle
they have the right kind of hardware fast path (e.g. TCAMs) built in
to accomplish what you want to do.
Heck of a challenge though. I haven't heard of anybody putting
together a white-box fast path router before.
