According to the section 'Armor Cap' on this page: http://www.uesp.net/wiki/Skyrim:Armor the cap is 567. Before I figured this out, I was happily walking around in heavy dragon plate with an AC of 1100. Now I just wear the Arch Mage's robes and cast the Alteration spell Dragonskin which matches the armor cap for the duration of the spell. (Yes, it does get tedious casting it over and over so I may ditch this strategy in the near future).
