Is it Worth?

Solution
A top end gaming cpu might gain you 10-20%.
But it seems a waste unless you have no budget constraints.
Updating your graphics is likely to gain you more, particularly for fast action games.
I have an Alienware aurora R4 with a x79 matx Mobo and a i7-3820 Cpu. 8gb DDR3. I was just wondering if upgrading to the new gen Z170 would be any benefit in hardcore gaming . I would basically like to have a boost in performance if its much.
