The only stat cap I can give you with any certainty is INT, which is 317 or 318.

STR testing is painful due to the STR:ATK conversion mucking up the results. Lots of data plotting, incremental changes and boredom, which is more than I'm willing to invest on a system that has a month to live.

If you have two or more sets of gear on hand, you could parse them against each other and use whichever prevails until 2.0. It's not useful for the community, but it'll give you peace of mind.
