Hi,
if you are optimist like me buy 2 socket box with intel 82599 cards
and with more than 200MB of RAM which is enough for one full BGP feed :)
At first i would buy one 8-core CPU with higher GHz as i can, and when,
and this is optimistic part :), openbsd gets multiqueue ix stuff and RSS
on top of it i would buy second 8-core CPU because it seems that 82599
is having 16 RSS queues.
For now you can get max 1Mpps with only plain routing without any pseudo
interfaces or pf.
