Go with an IB CPU (i5-3750k will do fine), and the ASRock Extreme4 Z77 motherboard.
16GB of RAM is excessive... get 8GB (make sure they're 1.5v). Your GPU is rather weak... try a Radeon 7850 or a 7870, if you can step up to it. I suggest the MSI Twin Frozr II OC edition. Apart from that, everything is fine.
Above is fine, but again... switch out the CPU with IB 3570k, or, if you can't wait, an i5-2500k. Overclocking is a good idea, ESPECIALLY because he indicated a cooler... if you're not overclocking, stock cooler is fine. His motherboard is fine, unless you are going IB, in which case the Extreme4. PSU also looks bad... many reviews say it's dead. Try Silencer Mark II for another cheap but good PSU.
