Update:
Latest Ubuntu 14.04 update has corrected connectivity issue.  Full 70/70 connection on AC wifi on 2.4ghz, as well as 5ghz.

Testing on both 3.15RC3 kernel as well as 3.13.0.24 kernel - stability
and connectivity improved.

Seems to be a non-issue at this point.

Status in “linux” package in Ubuntu:

Bug description:
  Desktop machine with Intel AC7260 + Bluetooth drops AC 5ghz wifi connection. No definitive pattern, but seems to drop more often when running Transmission torrent client and while using ssh to connect to home server.
  2.4ghz N wifi is stable - 68-69/70 connection
  5ghz AC wifi unstable - usually 52/70 connection
