If you can do all your peering based on Ethernet connections, 6500
with Sup2/MSFC2/PFC2 or better can be *very* good for BGP peering.
We're very happy with our 6509s used for just this purpose. We have
several full and partial views on each 6500.

Note that Sup2/MSFC2/PFC2 with full routing tables no longer work
with uRPF due to the size of the routing tables.
