Look for help building a $2k gaming system

Hello, TH community I am currently working on building a new gaming rig and was hoping for a little advice. Ive built systems before but its been a few years thanks to my my M17X laptop. Unfortunately said laptop is now showing signs of age that no longer make it my friend when it comes to hardcore gaming, so i decided to take the plunge and build a new desktop. Only one issue Ive been out of the system builder game for so long that I'm really have a hard time deciding on a motherboard. I'd be grateful for any advice about a mobo and processor cooler that would handle possible overclocking in the future. If you could give a sanity check on the parts Ive picked so far that would be great also. The types of games Ive looking at playing are things like Wow, Diablo 3, Starcraft, Skyrim and so on.
