I am running a second hand thin client, HP T730, very affordable, it has a single card slot populated with a Intel I340 4 port Nic (you want the I350 if you want to virtualize) it routes my near 1gig connection (850-950 cable depending on the day) with with the CPU hardly breaking a sweat.
But I am not running any packet inspection or intrusion detection, from my understanding that is a more CPU intensive task.
