will kabylake be a big improvement over skylake

Solution
The last several Intel generation performance gains have been marginal. I don't expect Kaby Lake to be a huge performance gain over Skylake, just a tweaking and marginal upgrade over Skylake.


As far as I know Kabylake will not be a huge jump, it is essentially an updated skylake architecture on the same socket.
There will be very marginal gains over skylake, so if you're building a PC, go for skylake now, and if you're waiting to upgrade wait for cannonlake unless you're an crazy enthusiast and want the top speeds on the market.
 


yes for most games a i3 will do just as well as a i5 or i7 it will only struggle on a few games. wait till something worth buying comes out
