if gaming is the aim of the build, spend a little less on the cpu say something like a 4440 which is plenty for gaming, get a h series motherboard and spend whats saved on a r9 290. for even more gaming performance.
overclocking cpu's are nice but there not needed for gaming rigs no matter how loud the fanboys scream...
