What would be the approximate perfomance for this 3 builds

[DHGAME]

What would you guys say would be the approximate difference in performance for this 3 machines for gaming now, in say 2 years and if they were overclocked. I am looking to see if a couple of hundred bucks will buy me more time and performance.

Two 7970 GHz edition will pretty much destroy any game you throw at it but the 3770K is not needed for gaming. Get the 3570K instead.
