I don't know what your motivation is, but 60fps is simply not possible. I bought one now (8G/512G) and hooked it up to the 4K TV.

At native 4K and max settings, it's in the low 20's.

At 1920x1080 and max settings it's at ~35fps. To get it close to 60fps it needs level 7 details at 1920x1080. That's in non-crowded typical quest areas.
