Again, there's always the question of what a border router is doing.
Raw forwarding speed isn't necessarily the defining factor, if the
router has to do extensive policy or QoS processing. If the 6509's
CPU isn't responsible for forwarding, then it may have more cycles
available for these processor-intense functions.
As to the question of importance of fast forwarding, how fast are the
lines to the outside world? If, hypothetically, you were running a
couple of T1's, both the 6509 and 7200 are overkill.
