Get the 1055t, on air or water it clocks almost exactly the same. I run my 1055t at 3.9ghz on the factory AMD heatsink, they clock very easily.
But as far as FPS, I wouldn't count on anything, optimization is usually the last thing that Blizz worries about when setting up the high end options. I mean wtf, 15fps in dala on my setup is very aggrivating, but my old 720BE and 4870x2 got 15fps, and before that my PI 9850 and 2x 3870's also got 15fps, seems no matter the syste, if you run the max settings that that system is capable of, 15fps.
