[Black Axe]

Well, Basically- I am looking to purchase a PC that would run the latest games, So yeah- I don't really get how does the processor speed work, Like- I've heard that the i5 & i7 processors are the best, What about the 2.8 / 3.2 / 3.5 GHz processors speed ? Are those bad ? And.. Which speed would be good to run all [most atleast] the latest-PC games ?

I know that I do sound annoying with my many questions, But yeah- I would really love to know,

Thanks in advance.
