What will last longer for gaming i7 or i5

im building a new rig and i wandering i7 or i5 and im wandering what will last long for gaming and day to day use 

It's kinda obvious that a better performing processor (i7) will last longer, but you don't need it for now if you aren't video editing.

Btw wandering= To move about without a definite destination or purpose.

      wondering= Think

i5 and i7 are pretty much neck and neck, only difference is the threads
