Wom't make a difference with any current OS, none of those would work with the new arquitecture, way different from the current one. One thing is the new hardware and another is the current lack of any soft or OS for it. Not even DOOM would run in it. Maybe in one or two years it would make sense to change your PC.
Another alternative to silice are diamonds, there the chips are with the same arquitecture as those from silice, but with the advantage that they support much more heat to the point that they don't even need refrigeration, apart the electric apabilities of diamond is way better as those from silice, that permits a way higher speed and stability. The price isn't much higher as the one from normal chips with sythetic diamonds. They are already in use, even with manufactories in Spain.
