hi buddy. i would reccomend to get msi g65 as most guys gets stable oc'es on them. And if ur looking for max oc u need atleast corsair h80i. My personal recommendation is corsair h100i or h110 as haswell get extremaly hot. Then u have just about 10% chance to get one of them good chips that would actually oc to 4.7ghz @ considerably low voltage. Hoppfully u get one mate.
