An Athlon64 3200+ should be sufficient for 200-400 MBit/s in each direction
with HTB and traffic accounting. At least it works for me. However, if you
start using tcpdump, your CPU usage will go through the roof.

Suggestion: Use oprofile and find out what demands the most performance in
your setup, then fix that and retest.
