Hello, guys, good morning.

So, I currently have an i5 4690 + GTX 1070. Although I've played in a 720p monitor (planning to get a 1080p one soon), which is overkill witht that GPU, in some games (Assassin's Creed Origins and Ghost Recon Wildlands), sometimes the 60 FPS can't hold steady in some critical points when there are many people and houses, also in some moments of explosions. Also, I've noticed that my CPU goes to 100% in those games and some others (For Honor, Nioh, Dark Souls 3 and I'm predicting it'd too in Witcher 3), whilst my GPU stays at a maximum of 92%.

Alright, the thing is: those 92% (GPU) I currently do with an i5 results in the same performance as if my GPU did 92% with an i7 4790? Will those problems of not holding steady 60 FPS go away upon changing CPU (despite playing at 720p for a while)?
I'm worried with the overall performance gain with that CPU. Also, does my Corsair 650w handle the rig well without worries? (My config is at the end of the post)

Motherboard: z97M-PLUS Asus
GPU: GTX 1070 - Galax Sniper White EXOC 8GB
RAM: 2x8GB 1866 Mhz Hyper X
HDD: Seagate Barracuda 2TB
SSD: Samsung EVO 850 250GB
PSU: Corsair CS 650M
Mouse: Logitech g502
Keyboard: Corsair Raptor K40
Windows 10 64 bits

Thank you.

If you play at 720p, it put more work load to your CPU. If you play at 1440p, it put more work load to GPU. That being said, you should upgrade tmonitor to at least 1080p so your current i5 4690 and GTX1070 is more balance. You will have more fps if you have i7 4790 and GTX1070. If you want steady 60fps, you should get Gsync monitor since you already have Nvidia graphic card GTX1070. You should go for Gsync 144 hz monitor 1080p or 1440p.

This is my rig

I have been considering an upgrade for months and months. I've asked questions here. I've looked at comparison videos between my 4690K and the 4790K. I've considered Coffee Lake. Because of all that I see this as an issue with game optimization or some other issue. Those are of course two of the most CPU and GPU hungry games out there. If you can find one for $150 then I might upgrade but I don't see the 4790 solving your issues. I do see Z97 and 4690K. What does overclocking do for those 2 games.

I might suggest a I7-4790K instead.
At stock, you will get a clock increase from 3.5 to 4.0.
In addition, your motherboard will allow you to overclock, perhaps to the 4.5 level.
Plan on better than a stock cooler also.
If you have 160mm available in your case, a $35 scythe kotetsu is an outstanding 120mm cooler.
The absolute best would be a $90 noctua NH-D15s.

No worries about 650w with a GTX1070, You could even do a GTX1080ti.

By the looks of it, the 4790 is a more casual choice to handle the future than K processors (either i5 or i7), right?

It's that I don't feel comfortable with overclocking and such, that's why I chose the no K version. I was looking for unlocking the power of my 1070, since I feel it does its job keeping 60 FPS, but sometimes when a hard task is sent to the CPU (already working hard to allow the GPU to work), it rains on the parade because it just can't do the job when games demand.

Regarding its temperature, I also got a GC Gelid Exterem to pair with my TX 3 EVO, since my case isn't that big but its cooling system is pretty good: 2 frontal fans, 2 exhaust fans upward and one on the back.

Future-proof wise (since open world CPU bound games are becoming a trend), my choice for the i7 4790 will keep me fine for years, right?

Nobody knows what will be needed in 5 years.
A rationale for the i7-4790K over the I7-4790 is that at stock, with no overclocks, the K runs faster. The 4790 runs at 3.6 while the 4790K runs at 4.0 without any overclocking at all.
For the future , the small premium you pay for the k is worth something now, and in time when/if you want to overclock, the option will be there for you.

I'm aware the K version brings some good benefits, but it was over $300 more expensive than the standard version. Also, the K one, OCed or not, would require me to have a good watercooler (so I've heard), whose maintenance troubles me a bit. I do recognize its power though.

I'm been using a 212 Evo for well over a year now with my 4690K. It usually is between $25 and $35. The Cryorig H7 is a bit better and similarly priced. Overclocked(4.4) or not the 212 keeps the temps. in the safe zone.

On ebay, I7-4790 sells for $200-$250.
I7-4790K sells or $250-$300.
I am surprised by your $300 more figure.

As to coolers, I really like the scythe kotetsu, a $35 cooler.
It is better than the hyper212 and even the noctua NH-U12s in this review:
http://www.silentpcreview.com/article1391-page1.html

As to a liquid cooler:
My canned rant on liquid cooling:
------------------------start of rant-------------------
You buy a liquid cooler to be able to extract an extra multiplier or two out of your OC.
How much do you really need?
I do not much like all in one liquid coolers when a good air cooler like a Noctua or phanteks can do the job just as well.
A liquid cooler will be expensive, noisy, less reliable, and will not cool any better
in a well ventilated case.
Liquid cooling is really air cooling, it just puts the heat exchange in a different place.
The orientation of the radiator will cause a problem.
If you orient it to take in cool air from the outside, you will cool the cpu better, but the hot air then circulates inside the case heating up the graphics card and motherboard.
If you orient it to exhaust(which I think is better) , then your cpu cooling will be less effective because it uses pre heated case air.
And... I have read too many tales of woe when a liquid cooler leaks.
google "H100 leak"
I would support an AIO cooler only in a space restricted case.
-----------------------end of rant--------------------------

Your pc will be quieter, more reliable, and will be cooled equally well with a decent air cooler.
