Upgrade i7 4790 or Get gtx 1080 (ti)

[Venom_]

So i currently have an i7 4790 (not k) on a pretty crappy gigabyte board with 16 gb of ddr3 ram and a gtx 1060 6gb. I also have a 144hz monitor and a h55 cooler. Im now thinking of upgrading at christmas to either a i7 7700k which means new board, and ram, and new psu because i may aswell do i complete change as i have a pretty lousy aerocool 600w integrator, or if i should upgrade to a gtx 1080 (probs evga ftw). Dont tell me that i shouldnt get one for 1080p gaming, i might upgrade in the future but to be honest you need at least a 1070 for consistent over 60 fps in say must triple a games, or pubg and destiny. Im using my pc for gaming and also some editing here and there. i have 2 ssds and a hdd and have to put my hdd into my sata 2 ports because my mobo only has 2 sata 3's.

I have already asked this before but would like more opinions

for gaming, there is no difference between the 4th and 7th gen on the same clock. even without overclocking, 4790 is more than capable today.
and for 1080p@144Hz, a normal GTX 1080 (non Ti) is more than enough for the next couple of years.

Upgrade PSU and GPU only. CPU upgrade to i7-7700k is of little benefit.

Get the 1080 Ti you will see more preformance boost with it than you will with upgrading your processor, (unless your building a workstation for things like content creation, compiling, 3D design, ect.)
