I'm thinking about upgrading my router with an AC capable router. My current router is 2-3 years old. It is working fine, but it doesn't have AC capability. I did a quick search on Amazon and it seems like all of the AC capable routers are pretty expensive. Significantly more than the average ABGN routers. Is the speed difference between the two really noticeable? Is it a worthwhile upgrade switching from a perfectly good ABGN router to an AC router? FWIW, I have a 2013 MBPr which has AC capability. I'll have an iPhone 6 soon, which can also take advantage of it. And I have an Apple TV 3, though I keep that hardwired to the router so wireless doesn't really matter there. Thoughts? Suggestions on an AC capable router that isn't really expensive?
