Building a Computer Help

Well I am building my first ever PC. I have some parts, and it is mainly for hardcore gaming. I have a 2k budget and I would like to get the most out of my money. I am planning to play Skyrim, Crysis 3, Tomb Raider, and future games at at least 70 fps. I have a Build already set up, and I need TONS of advice. (Yes it is capitalized). I am definatly open to anything that does not alter the case, I love the case I have chosen and am willing to stick with it. Other than that I need suggestions for my build. Amd Or intel, Amd or Nvidia I am NOT a fan boy, I rely on cold hard facts. Now to my Build:
