MasterLuc :
how much of a performance difference is there when you overclock an i7 4770k with a hyper 212 evo and if not much is there a similar cheaper intel i7 product
Hey Luc-
The i7 4770k is the cheapest processor in the current i7 line up- unless you can get an Ivy Bridge i7 3770k. Based on your cooler, you should be able to get a 4.2ghz OC (maybe?), which is around a 5-20% difference in performance, it basically isn't noticeable, but it still is, and may help in rendering.
Out of curiosity- what editing suite do you plan to use and what GPU do you plan to get?
