Hello!

I curently have an i7 2600k paired with Gigabyte GA-Z77-DS3H rev. 1.1. The problem is this board does not allow overvolting, so I cant go further than 4,3 Ghz. I want to get a new motherboard to overclock my CPU to the max. I have to choose from the ASRock Z77 Pro4, the ASRock Z77 Extreme 4, the ASRock Z68 Extreme3 and the Asus P8Z68-V PRO GEN 3, all second hand. What should I get?
