Difficulty choosing between 2 builds

[JohnnyGui]

Hello guys,

I have a dilemma choosing between 2 gaming builds. I am not planning to upgrade it further for a while. I want to play on 1080p @ 60Hz. Games like GTA V, Witcher 3, Shadow of the Tomb Raider, AC Origins (& upcoming Odyssey).
The 2 most important things for me are the gaming performance in terms of FPS (no streaming or multitasking during gaming whatsoever) and the degree of being future-proof regarding gaming.

Here are the 2 builds

Build 1
CPU: i5-8600 (non-K!)
Mobo: Gigabyte B360M Aorus Gaming 3
GPU: Gigabyte GTX 1070
RAM 16GB 2400Mhz
Storage: NeoForza 256GB SSD SATA600
Power: Cooler Master ATX 2.31 700 Watt
Case: Cooler MasterBox MB500

Build 2
CPU: i7-7700K
Mobo: Gigabyte Z270P D3
GPU: Gigabyte nVidia GTX 1070
RAM: 8GB 2400Mhz
Storage: NeoForza 256GB SSD SATA600
Power: Cooler Master ATX 2.31 700 Watt
Case: Sharkoon VG4-W ATX

Build 2 is about €20-30 more expensive. My biggest doubt concerns the difference in RAM and CPU (i5-8600 + 16 GB RAM versus i7-7700K + 8 GB RAM).

I would really appreciate some advice on this.

Hey, I would definetly go for Build 1 but with an i5-8600k unless you have instead of gaming applications in mind that might benefit from hyper threading.
What is missing in both builds is a capable CPU cooling.

Build 1 is much better.

Thanks for the advice guys. I read that the i7-7700K would be better overall in gaming performance than the i5-8600 (non-K). But does the double amount of RAM with the i5-8600 give a more significant performance boost than the i7-7700K with 8GB of RAM?

RAM...depends. There is today only limited no. of games who might have troubles with 8GB. What is more advantages for the i5 is the real 6 cores instead of 4 cores with HT on the i7. Thus I stick to my reommendation to go for the i5-8600k

Ok, regarding build 1, I got the offer to have the i5-8600K instead of the non-K version for the same price.

However, to be able to overclock it I'd need another motherboard than the one shown in my OP (it has to contain a Z370 chipset)
The seller offered me to choose between the 2 following motherboards:

- Gigabyte Z370 Aorus Gaming
- Gigabyte Z370-HD3

I am kind of reaching the limit of my budget and the Gigabyte Z370-HD3 is about €22.5 cheaper. Would the difference between these 2 motherboards have a noticeable impact om gaming performance?

I have another question. I am not planning to overclock the i5-8600K for a while until I really need it. During the non-overclocking period, would the Intel stock cooler of the i5-8600 (non-K) be enough for the i5-8600K regarding temperatures?

It will be good enough.....just barely...But as quickly as you can, get the better cooler AIO if overclocking is in the pipeline...

Just barely? Do you perhaps happen to know the estimated idle temps when the Intel stock cooler is used for a non-OC'ed i5-8600K?

UPDATE: Just heard that they will use a Xilence i250 cooler for the i5-8600K and that it will give temperatures of 75-80 degrees at full load. Is this the average for a non-OC'ed i5-8600K at full load?
