Is there a reason for the 2600k cpu , you can save $100 by going with the 2500k and get the same overcloking and virtually the same performance. The main difference between the two cpu's is the 2600k has hyperthreading and games just don't take advantage of the feature. Are you considering a SSD for the OS , I don't see one listed.
Thermaltake TR2 RX 750 W is, according to our methodology, a flawed product that must be avoided at all costs. It can’t deliver its labeled wattage at high temperatures, but this is not the worst of it: ripple and noise level are way above the maximum allowed when you pull 80% or more from the unit’s labeled capacity (i.e., 600 W and above), overloading your components (especially electrolytic capacitors from the motherboard and video cards), which can cause your PC to present an erratic behavior (crashes and random resets) and, under extreme conditions, damage components.
This fixes everything, PSU is 10.0 performance rated, increases fps by 40% and adds Blue Ray for less money....plus loads of expansion room and MoBo is Gen3
