Okay, so the NPE-G2 won't help.

Your decisive factor then becomes how many routes you want to hold. A
switch would be great for peering from a forwarding performance
perspective, but you can't hold a lot of routes. Also, BGP features may
be restricted compared to a typical router (yes, the ASR920,
ME3600X/3800X and ACX5000 can be thought of as routers), but then you
can't scale the FIB.

Assuming you're using the router purely for peering, you'll likely be
holding about 40% - 50% of the global routing table at the high-end. So
you can use older, cheaper hardware-based routers like the Juniper M7i
or Cisco ASR1002 (the latter being the better option of the two).

As you're going to push beyond 1Gbps, you can consider a LAG to keep
your costs down. If you have to consider a 10Gbps port, then your price
could go up, but you'd still be okay since you can pick these up on the
used market for a reasonable price.
