asrock extreme 4 and MSI's SLI krait edition are good choices from that tier

even if you get a good mobo , if you dont have efficient cooling you cant hit your 4.5ghz OC target
 
depends on your vcore. i would say tier three limit is 1.30v otherwise you will try the motherboard vrms and mosfets over time. tier 2 should be able to handle 1.35v, but you will need something better than a dual 140mm phanteks/noctua or h100i. tier 1 should safely handle 1.40v all day but you will need a real 240mm copper rad with a nice pump and fans if you want to run that all day.
