Well guys, this is my final build http://pcpartpicker.com/p/3Dndy, will be overclocking GPU(Max OC), RAM(@ 2133Mhz) and CPU(4.5Ghz), and my question is, do i need a thermal compound or something extra for the cooler, and also want to know if all my components are perfectly paired. Thank You guys for all you're help.
