Is the i7 6700k a good upgrade from the i5 3570k for 4k gaming?

My graphics card is a GTX 980 TI. I want to be able to use DX12 (will have to pick up Windows 10, first).

For gaming it's not a big jump, and you're not going to see a big boost unless DirectX 12 allows the i7s hyperthreading to make more of a difference in gaming compared to the i5s. Your 980Ti is DirectX 12 compatible and once you have Windows 10, you'll have that taken care of. I'd say stick with what you have right now unless the new features on the Z170 chipset really interest you eg. more chipset PCI-E lanes allowing the use of 2 way SLI and a high performance SSD at the same time on a mainstream platform.

Yes but you could do much better. You could save money with the i7 4790k which is fast. The 6700k though is even slower than the i7 5820k especially gaming. Look at the cores and memory sections here.

4K isnt worth it... do some research 1080p vs 4k... def not worth performance hit imho
