Cat 7 is mostly overkill.

Even Cat 6 is more than enough, since the performance and throughput you get is still dependent on the rest of your network infrastructure - i.e. router ports, switch ports, PC ports. Those on consumer devices are just capable of low to medium levels of Gigabit (10/100/1000) traffic.

And being in a residential setting, you will almost certainly never reach saturation/capability of Cat 6, let alone needing Cat 7.
