currently have the ASROCK Z87 Extreme3 + 4770k + 780gtx oc pny + 16gb some g skills.... basically would it be worth upgrading to a ASUS MAXIMUS VI FORMULA? I currently have liquid cooling but only oc'd to 4.0 ghz on the 4770k. Other than the mother board's feature's is it worth upgrading? Basically only use for gaming at 1080.
