Asus Z87-K
Cons: Only 1 PCI 3.0 socket.
He doesn't want or need a 200$+ motherboard. If he is only using one GPU, there is no need for more than 1 pcie 3.0 slot - if you want SLI, you want a pricier motherboard. Soundcards and that type of thing certainly don't warrant PCIE 3.0, the only time that additional 3.0 slots are ever of use is for a PCIE SSD (very expensive, out of reach for most folks) or SLI video cards. And if you want SLI you'd need a pricier motherboard....
Anyway, the 150$ Asus K will do the job just fine, and will OC the CPU just fine. I'm not sure about the cooler, as i'm not able to load the website mentioned - but i'm a big fan of closed loop coolers. The corsair H50 should do you well if it fits in your case, OP.
