Id say this is a good thing for consumption of energy across the world.
At the moment gaming wise, processors havent really netted any solid performance boosts. As we increase resolution the demand of the cpu has decreased as the gpu takes the strain.
I hope we see better programming to ensure we could utilise the cpu much more effectively in the future so that boosts in coming cpu builds become more practical. At the moment other than board features (m2, ddr4 ect) i see no reason to upgrade from sandy bridge.
