the skylake would be a great thing to wait for, but would it really be worth it for you right away, would be the question i would ask first. if it is going to have ddr4, and is anything like the haswell-e, then it may have completely different ram slots, so no using old ram, in the new build. also, it will mean a GPU upgrade possibility for you in the future for PCI-E 4 (i would assume would be backward compatible to PCI-E 3). As the ddr4 is right now, cost of these components may be a bit inflated right at the start.
