Is Ryzen not an option? I would wait to see what AMD comes up with when they release 6 and 4 core cpus. Their 8 core chips are doing really well.
If you are ready to build and you want to go with intel, just go for it now. Intel's performance improvements have been minimal and it is generally not worth the wait. The only exception is if you are considering AMD but do not want an 8 core (wait for their next release)
