Once again, not true. NAT and QoS are the most expensive tasks a consumer router will perform, and even at 1Gbps it's rather mundane work even for a slower CPU (the 600MHz CPU in the RT-AC66U is sufficient). Once you start looking at the latency requirements to achieve 10GBps interconnects you're going to have issues with what you can reasonably expect from the $200 price range, but consumer networks have a long ways to go before that's going to even need to be thought about.
