Upgrade i5 6600 to i5 8600k worth?

[cemozayface]

Should i do it?

No there is not so much of performance increase but the only thing you can do that is overclocking with your new system

 

[cemozayface]

What about going for i7 one.I want to uprage my pc once since years

Worth is something only YOU can determine.

A jump from a I5-6600 to an overclockable i5-8600K is a massive jump in cpu capability.
Not only do you get 6 cores vs 4, but you get an increase on clock rate via overclocking from 3.3 to 4.9 or so.

If you meant, I5-6600K, not I5-6600 with an overclock, the clock rate is not so different so the main benefit would be more cores.
Not really a biggie for gaming.

Thanks for answer.My current rig is like this

i5 6600,gtx 1070,32 gb ram

Other than cpu uprage,should i consider going for gtx 1080 ti too or just wait for new series to come

My goal is playing games in ultra and streaming from time to time

Do the cpu upgrade first and see how you do.
If you need more graphics power, then consider a gpu upgrade.
Not likely, I think unless you favor fast action games at 1440P

MERGED QUESTION
Question from Cem___ : "Upgrade i5 6600 to a i5 8600k worth?"

Is it worth for gaming&streaming?

it would be because the 8600K has 6 cores while the 6600 has 4. but if you upgrade to the 8600 know that you will have to buy a new motherboard too

Yes, it would be a significant upgrade.
though for both gaming and streaming an i7-8700K would be more appropriate as those extra threads would be helpful.

That is a winning upgrade.
Not only do you get more threads, 6 vs. 4,
but you also get a significant boost in cpu performance per core.You are looking at a jump from 3.3 clock to 5.0

^ there is no IPC gains for gaming from 4th gen to the 8th gen. it's just the clocks are a bit higher. so boost per core yes, boost per clock no.
but I guess you just mistyped

That's not really helpful, giving him base clock on the 6600 vs. a potential OC result for the 8600K.

• 
  ■ i5-6600: 3.3GHz base, 3.6/3.7/3.8/3.9GHz Turbo with 4/3/2/1 cores in use.
  ■ i5-8600K: 3.6GHz base, 4.1/4.1/4.2/4.2/4.2/4.2/4.3GHz Turbo with 6/5/4/3/2/1 cores in use.

The extra 2 cores will help in some multi-threaded applications, but the primary benefit for streaming is that you can have 1 or 2 cores handle the streaming while you still have 4 cores for the game. For strictly gaming without streaming, most (> 95%) of the games out there will ignore the extra cores.

While you get the potential to overclock with the 8600K, depending on your current motherboard you could simply drop in an i5-6600K (or, most likely, a 7600K once you've updated the BIOS) & overclock with it -- or even get an i7-6700K/7700K (giving you not only OC potential but also additional threads for streaming).

The problem is that you will have to buy a new motherboard (8600K is not compatible with 100- or 200-series motherboards), as well as a CPU cooler (Intel doesn't provide one for "K" CPUs, as they assume you're going to overclock).

Currently, the i5-8600K seems to be running about $280 USD (https://pcpartpicker.com/products/cpu/#f=85,75,73&s=12,13&sort=price&page=1). That's about $60 more than the i5-7600K (3.8GHz base, 3.9/4.0/4.1/4.2 GHz with 4/3/2/1 cores); the latter would give you nearly the same per-core performance (especially OC'd), plus you wouldn't have to spend the $112+ USD for a new motherboard. Heck, at $319 USD the i7-7700K is cheaper than the 8600K & its motherboard ($392 USD or more).

Going to Coffee Lake makes sense for someone with a pre-Haswell system (or, depending on their current CPU, even someone with a pre-Sandy Bridge/Ivy Bridge system), or someone who is looking for a feature on the Coffee Lake motherboard that their current board doesn't support. In your case, though, your system is way too new to really benefit from it, at least not for the price.

^ there is no IPC gains for gaming from 4th gen to the 8th gen. it's just the clocks are a bit higher. so boost per core yes, boost per clock no.
but I guess you just mistyped

True, I meant potential performance per core.

I might point out also, that a upgrade from a I5-6600 to a I7-7700k is also a very good upgrade.
I7-7700k is a very good performer at stock regardless of the motherboard.

^ but an upgrade to 8600K would be cheaper and have same performance and a bit better thermals compared to 7700K

You can upgrade to a I7-7700K running at stock in any lga1151 motherboard.
If the motherboard is z170, you can also overclock.
7700K might a cheaper upgrade because you do not need to change out your motherboard.

OTOH, you can buy a Z370 based motherboard for $130 or so, making the 7700K and 8600K upgrades comparable in cost. If equal, you will get more for your money with the 8600K route.
