Now let's sit down and talk about it. This new cpu needs a new socket. That means a whole new mobo. LGA 1150 (Broadwell and below) won't fit the new 1151 socket type. Bit of a bummer but there are some pros.
Pros:
Can support DDR4 ram
Can support more PCI lanes. (more hdds, ssds, etc.)
Better thermal hardware vs. last generation
FIVR (fully integrated voltage regulation) has been moved off cpu. Meaning cooler temps and possibly better OC'ing.
Cons:
Very small performance gain from Broadwell to Skylake (5%)
New socket = new motherboard
Uses more power than previous gens
Same 14 nm architecture as 4770k and 4790k
Overall thoughts:
I would not recommend upgrading to Skylake if you have a cpu from the last three gens (Broadwell, Haswell, Ivy Bridge). If you have an i7 3770k, i7 4770k, or i7 4790k, I would not recommend upgrading. The price for this new socket just doesn't seem worth it. The performance is not worth upgrading.
