Anyone got the new i7 Processors?

I was looking to build a new PC and was wondering if the new 6th gen i7 Processors are any good, I was looking online and have seen some mixed reviews.

What are your thoughts on the i7?

I am using i3 processor. But one of my cousin using desktop computer with i7 processor. It is faster than mine, but not that much. After using it I don't think I will pay more for i7 processor. Instead of that I will go for i3 and i5 processor. Well, I don't have gaming experience with it, so can't comment on it.
