Well, my experience with the 4770k non-OC is that it will run hot. Mine was hitting close to 70C when my Water block was not working right. Now it is a solid 30C. I went with Noctua since I am positive it will keep that CPU cool. My friend is not the one building it. I am. I will build it and ship it to his duty station in Okinawa, Japan. The $54 wifi is an Intel AC wireless which will assist him on base with Internet connections. There is no guarantee that he will have Ethernet provided to him in his housing. So, having the AC wireless would be a big boost. Granted, if I went with a board that had a mini-PCIexpress slot, I could do it for $35 for the same chipset. If I were to drop the keyboard and mouse I could change the 760 to a 770. The build will not happen until this fall though when he is at his duty station and has accumulated the necessary funds to get the parts, pay me to build it, and ship it. He originally wanted to go AMD for everything but I convinced him to go Intel for this build.
