No, it won't route 80Gbps, because any single flow on a CCR uses a single core on their multi core Tilera CPUs. The CCRs struggle to really do 10Gbps of real world IP transit traffic.
If you're pushing 5Gbps+ of your customers' IP traffic in a daily sine wave pattern to/from upstream and adjacent BGP peers (paid IP transit and peering at a local IX), and have $2,500 to spend, you will be MUCH better off buying a proper routing platform that has things like hotswap fan trays, hotswap 1+1 or N+1 power supplies, redundant hotswap routing engines, etc. You can do this with a used/refurb Cisco or Juniper for the same price as the higher end Mikrotiks. I can build a Cisco 7604 or 7606 with dual RSP720 for less than $2000.
The CCRs have a single motherboard in them that is about the same quality as a $85 PC motherboard. If you're running an ISP that is moving multi-Gbps of customer traffic and have potentially thousands of singlehomed customers downstream of you, do you want to rely on a 'core' router that has absolutely zero hardware redundancy?
Mikrotiks have their place at edge and small aggregation but when you start talking about things that are $2,000+, please, buy a real router.
