Time to upgrade? Ivy Bridge i7 to Coffe Lake i7

[poopflinger]

I'm curious if anyone would recommend upgrading my current system to achieve optimal FPS in 4k gaming at 60hz. Currently I can achieve close to 60fps average on most of the AAA games, but the 1% and 0.1% lows can get into the 30s. I'm curious if upgrading to a modern CPU, chipset, and RAM would mitigate the drops in FPS. Currently gaming at 4k @60Hz.

Current:
i7 3770K @4.5Ghz OC
ASUS P8Z77-V PREMIUM motherboard
32Gb DDR3 2400Mhz RAM
ZOTAC GTX 1080 Ti AMP Edition

Theoretical:
i7 8700K @4.8 - 5.0Ghz OC?
ASUS ROG Maximus X Hero motherboard
32Gb DDR4 3600Mhz RAM
ZOTAC GTX 1080 Ti AMP Edition

Thanks in advance for the advice!!

You like ASUS a lot!
For 60 FPS, 3770k is still very capable. However, 6 core 8700k will help with those 1%. I will get this:

16 gb is more than enough for gaming.

Fps is all about the cpu, resolution is all on the gpu. Basically you'd get the same 60fps at 1080p as 4k from the cpu, it's the gpu that makes the difference between the two.
That said, if that 1% is dropping to 30fps you have 2x options. Upgrade the cpu to something with higher IPC than the old 3rd generation cpus, or relax some of the cpu bound settings like viewing distance, grass details etc which hurt any cpu.

Nothing wrong with Vapour's choices.

However, one last thing to consider. The game engine. In more than a few games, there's areas that simply defy logic (like a certain stairwell in Crysis3) that are so badly optimized that even the meanest cpu/gpu combo you put together still sees drastic fps drops for no apparent reason. It's entirely possible that the drops you are getting in those games are simply always going to be there whether you just spent $900 on a upgrade or not.
