2.3 Mpps with a NPE-G2 at full routing table, I don't even think Cisco 
markering would say that should work.

I'd recommend a used Cisco 7304 instead, or a 7604 with Sup720 and a 6724 
LC, but that's also a bit overkill.

Otoh if you already have an Engine 2 or Engine 3 gig card in that 12008 of 
yours, it's a good packet mover and you should stick with it.
