I would probably start with a CCR1009 on each side. you'll get AES-CBC hardware offload and plenty of horsepower to reach a gig with EoIP.
The performance requirements largely depend on what kind of MTU and overhead you'll have and if you'll need to allow EoIP to frame fragment or not which slows down performance at higher rates and requires more CPU overhead.
