If you want to use the box for other tasks like squid, etc. you might become constrained. We use ours for some RRD polling.
I have a box with two full sessions of about 120k prefixes from transit
providers, both sessions with soft-reconfig enabled. CPU is never an
issue, as far more CPU time is spent handling ethernet card Rx
interrupts than BGP or OSPF updates. The box forwards an average of
11kpps and 60Mbit/sec, peaks around 16kpps and 90Mbit/sec.
