The shift over to 5 GHz should help in some ways... While it may have poorer range, I'm sure that the shift to MIMO, along with general improvements, will almost certainly bring better range than, say, 802.11a.
Speaking of that, the "AC" thing is confusing. Is it intended to be a successor to 802.11a? (for the uninitiated, it was a lesser-used standard that came out AFTER B, used 5 GHz, and had the lowest range, but G-level bandwidth; it wasn't until 802.11g that Wi-Fi could have the best of both the "A" and "B" worlds)
This letter-picking is really confusing: from "B" to "A" to "G," to "N," and now to "AC." I can overlook the B/A discrepancy, (technically, they came out in the reverse order they were first written up in) and I'd just assumed that "G" stood for "Gamma," the third letter of the Greek alphabet after "Alpha" and "Beta." 'course, "N" broke that sequence entirely.

CAT 5e will handle gigabit Ethernet. If you installed CAT 6, then it technically supports 10-gigabit Ethernet... For whenever they ever actually release them for home PC use. (to date, I only ever see it used as an option for supercomputer interconnects, though I believe it's lost ground to the likes of InfiniBand and HyperTransport.
