If by "max resolution" you're talking the full 2560x1600, trying to run any reasonably modern game on the Iris 6100 (only the 15-inch model has Iris Pro) will be unplayable. Using the scaled 1280x800 should be fine.
I play my games in bootcamp with Windows 8.1 and then I can play Civilization V, age of empires etc on 1920x1200 without problems. Of course the fans spin up but what do you expect
Civ 5 runs natively, though that's the only one I can suggest off the top of my head. You should check out the Strategy/Mac section on Steam, they've got quite a selection. If you want to go old school strategy then check out the games on Gog.com, a large majority of them run fine on OS X.
Endless Legend is supposed to be quite good. Been meaning to get it myself for a while. Its a 4x turn based strategy game like civ 5, but fantasy based. It's also considered to be a lot better than civ: beyond earth. You can find it on steam.
Homeworld and Homeworld 2 (The reboots not the original games) both work beautifully on Bootcamp Windows 10. I also play Civ 5 on Bootcamp vs Native (I have both and it's a little smoother in Windows).
The fans spool up and it gets hot.
