I am trying to keep the setup under $1600 while still being effective .Most of my usage will include intensive 3d application renderings , Gpu rendering and casual gaming . I am not planning to overclock the setup atm .
Overclock it - that is what the 'K' series is designed for. It's really easy to achieve an overclock on your proposed rig. Basically for the basic overclock you just have to change literally 1 or 2 settings in the BIOS.
Power supply is junk and way too powerful. With a single GTX 670 you need a quality 500w power supply. Stick with Corsair, Seasonic, PC Power and Cooling, XFX, Silverstone, Enermax, OCZ or Antec. Do not get Coolermaster or Thermaltake. If you plan on adding a second GTX 670 go with a 750w power supply.
As said above the "K" model processors are made to overclock. If you might do it one day then get an aftermarket CPU cooler. If not there is no reason to get a "K" model processor.
