i5-6600K to i5-8600K - worth it?

[Robi]

I'm currently using the following build purely for gaming:

i5-6600K Skylake @ 4.5GHz
Corsair H60
MSI Z170A Carbon
Corsair Vengeance LPX 32GB (4x8GB) DDR4 3000MHz
MSI GeForce GTX 1070 ARMOR 8G OC

I noticed the bundle deal posted earlier today for the i5-8600K and Gigabyte Z370 AORUS. In essence I could re-use the RAM + cooler and upgrade the CPU + mobo for pretty much next to nothing. It would mean more cores, threads, cache and higher default clock, although I'll be overclocking it to similar if not more.

A couple of benchmark videos indicated an average increase of 18.1FPS in Arma 3, 36.5 in CS:GO, 27.8 in Watch Dogs 2, 18.1 in GTAV and 41.6 in Witcher 3; so fairly hefty increases across multiple games.

For the sake of circa £100, it sounds like a no brainer surely? I am planning to move from 1080p to a full 1440p build next year at some point, so this is just a stop gap until then.

With a GTX 1070, no point.

Wait for Z390 with 8 core chip if you want to upgrade.

How comes it is only a £100 upgrade?

I was going to sell the CPU + motherboard for around £200-225ish and surprisingly I had £60 cashback land in my Quidco account today. That pretty much leaves around £100.

What about this build would not be full 1440??
I have full 1440 on a E5 1650v2, I have to run 2 290x's but your should be fine with the 1070.

I don't have a 1440p monitor at the moment. If I'm chucking £400-500 into a ROG Swift 1440p monitor, I might as well change the entire build at the same time
