Hey guys, I just got teh i7 4770 for a good deal. I know there is the K version but i got the reg one for a good price. So i was planning on OC the k version but couldn't afford it. So can i still OC? I am aware the k means unlocked. And I do have an H80i cooler but i was wondering is it necissary to have a water cooler and im nto OC? I see that the water cooler without OC keeps good temps in my PC all around.
