I'm going with the i7-4930k for $179.99 for mostly gaming and minor video rendering. I am buying the cpu and waiting for a ddr4 mobo with a 2011 socket.
Current cpu's are almost definitely not going to work with the new ddr4 2011 socket motherboards. it's going to be a totally different 2011 socket. Hasewell-e has integrated voltage regulators and so the components are totally different on the motherboard side also.
