Asrock z68 extreme3 gen3 is a safe bet. I use it and many people recommend it. You should add a little money and buy the 2500k, which is easily overclockable to 4GHz with stock cooler and past 4.5 with an aftermarket one ( CM hyper 212 + ). Everything else looks good to me, except maybe the corsair vengeance RAM. Don't get me wrong, it's very good, but it's way too high. G.Skill Ripjaws 8gb ddr3 1600mhz will be great.
