Does the type of motherboard I choose affect cpu performance at all?

I originally bought my PC in 2014 and upgraded my outdated GPU and Monitor. I now plan to upgrade the rest of my build this year and I'm looking for great components and any advice.

2017 Upgrades:

GPU: EVGA GeForce GTX 1080 Ti FE

Monitor: Acer Predator XB271HU 27" IPS 1440p G-Sync 165hz

Current Old Build:

Case: Cooler Master HAF-XM Mid-Tower

CPU: Intel® Core™ i7-4770K 3.50 GHz 8MB

Motherboard: GIGABYTE Z97X-Gaming 3 ATX w/ Killer GbLAN

Power Supply: 850 Watts Corsair RM850 80 PLUS GOLD Certified Fully Modular Ultra Quiet Power Supply

RAM: 16GB (8GBx2) DDR3/1866MHz Dual Channel Memory (Corsair Vengeance)

- Any other potential components I should also upgrade? I'm currently looking at these parts below that some friends recommended. I have no idea what the difference is between the motherboards listed even though they are the same make. lol

Parts I'm Looking At:

CPU: Intel 8th Gen Core i7-8700K Processor

Thanks everyone, I'm trying to get back to mainly PC gaming after almost 2 year since I got my build and recently upgrading my gfx card and monitor. This stuff ain't cheap both cost me around 1600 dollars. Worth the quality.

@MonsieurX: you think it's bad game optimization by the devs??

I bought a 1080 Ti a week ago and it came with Ghost Recon Wildlands for free. I ran the game with almost maxed out settings and it seems that the fps drops from 60 to almost 44 and in between a lot of the times. In the future I wanna purchase Mass Effect Andromeda and want to max them out. I also just bought a new monitor with g sync. Do I have a bottleneck on my graphics card or does the game have issues currently? Thanks

My other hardware is listed below...

Monitor: Acer Predator XB271HU bmiprz 27" WQHD (2560x1440) NVIDIA G-SYNC IPS Display, (Display Port & HDMI Port, 144Hz)

CPU: Intel® Core™ i7-4770K 3.50 GHz 8MB Intel Smart Cache LGA1150

Motherboard: : GIGABYTE Z97X-Gaming 3 ATX w/ Killer GbLAN, 3 PCIe x16, 3 PCIe x1, 1 PCI, 1 x M.2, 1 x SATA Express, or 6x SATA 6Gb/s

RAM: 16GB (8GBx2) DDR3/1866MHz Dual Channel Memory (Corsair Vengeance)

@MonsieurX: is it worth running games at 4k currently? Seems like the 4k versions of the monitors you listed only are 60hz. I do play some fps games like overwatch. I also have a Samsung ks8000 that's 4k HDR+. Is that decent for gaming? I use it for 4k streaming movies from Netflix

@MonsieurX: i was looking for a 1080ti but I can't find them in Stock. Is the 1080ti a lot more powerful than the 1080? Also, what kind of monitor specs would you recommend? I've heard of BenQ, are they really good?

Hi everyone, I'm trying to get back into PC gaming and would like to be able to run most new games in ultra high settings. Money is not an issue currently with upgrading what I currently have. What would you guys recommend I upgrade from my tower and to what? I also am looking to upgrade my monitor if needed. Thank you.
