I am making a new system, and i am confused between asus p8p67 , asus p8p670- m pro & asus p8z68-m pro. I will use intel i5 2500k. And i will do a bit of overclocking , since i live in India so temperature will be a important factor. I dont have any intention of using sli/crossfire. All these boards are priced almost same, and i am very confused.
