Hello I am currently in the market for a new cpu and upgrade for my old set up which includes Core I5 4690k ( and ddr3 .

I am having a hard time deciding on what to get

we have:

1) Core i7-7700K ($280)
# cores Quad-Core
4
# of Threads
8
Operating Frequency
4.2 GHz
Max Turbo Frequency
4.5 GHz
L2 Cache
4 x 256KB
L3 Cache
8MB
Manufacturing Tech
14nm

2) I5 8600k ($250)
# of Cores
6-Core
# of Threads
6
Operating Frequency
3.6 GHz
Max Turbo Frequency
4.3 GHz
L3 Cache
9MB
Manufacturing Tech
14nm

3) I7 8700k ($400)
# of Cores
6-Core
# of Threads
12
Operating Frequency
3.7 GHz
Max Turbo Frequency
4.7 GHz
L3 Cache
12MB
Manufacturing Tech
14nm

spec wise the i7 8700k is winner but is the extra cost worth it? i7 7700k is also good but the fact i am buying older generation + motherboards which leaves any upgrade having to rebuy mobo once will increase price again.

my current cpu is : I5 4690k
# of Cores
Quad-Core
# of Threads
4
Operating Frequency
3.5 GHz
Max Turbo Frequency
3.9 GHz
L2 Cache
4 x 256KB
L3 Cache
6MB
Manufacturing Tech
22nm

what do you guys recommend? I am having an extremely hard time deciding.
Is it also true 8th gen cpu like the i7 8700k run extremely hot and require water cooling or super high end cooling just to run normally? I wiil use cpu mostly for entertainment set up ( mostly gaming,movies etc) I do not stream or anything like that. I notice now BF1 eats up my current cpu (even with a gtx 1080 i just bought). I also will be doing very very minor OC if anything at all.

Any information is massively appreciated.

P.S- is the I5 8600k an upgrade to the i7 7700k?

I am currently using 27 inch 144hz 1440p monitor i got from bfriday (dell tn panel one forgot model name)

Kaby Lake has worse temp issues than Coffee Lake, but they're both pretty bad.

If you're buying a new system, go Coffee Lake.

If you're upgrading an old system that already has a Z170/Z270 motherboard, just go Kaby Lake.

I am doing complete upgrade i don't have Z170 or Z270 ( as a matter of fact the mobo i want is never in stock since bfriday { asus rog hero 9 } )

I am upgrading my old Core i5 4690k which seems to finally being completely dominated by new games. ( keep in my in don't OC much if at all ) its running stock.

thank you for info by the way.

prices are different story tho

i5 coffee lake is 250 now in microcenter

i7 kaby lake 280-300 dollars

i7 coffee lake is 400 dollars ( MSRP is 380 also its a bit overpriced )

I upgraded from a 4690k to an 8700k, holy ****... that's all I can say. You are probably experiencing the same feeling of sadness as that i5 was a beast when I first got it. This 8700k is amazing though. Stock clocks dominate anything I throw at them. I had it stock on a Hyper 212 Evo and it ran fine (sub 80c). I decided to grab a Thermaltake Floe Riing 360 AIO and OC'd to 5ghz, now it completely annihalates anything and temps haven't been seen above 60 in games, and max at high 70s in demanding stress tests.

TL;DR Get the 8700k, friend has a 7700k, games like PUBG and Destiny 2 he runs fine but I squeeze a good 20-30fps on him.

7700K: No! 6 Cores > Threads 8 (in most cases)

I had this debate with myself. I have the money to 8700k, though all the benchmarks the 8600K OC was able to keep in pace with the 8700K OC in gaming. So that is what I went with, they both overclock about the same and the little bit of extra cache isn't going to do a lot for you in the 8700k. Very few things are optimized for hyper-threading. Most games have a very short life and won't last that long, so the developers don't make it efficient enough to take advantage of hyper-threading. Most reviews out there states the 8600K is the gamer's CPU, if you are hosting VMs or doing something else that really takes advantage of hyper-threading, then consider the 8700k. If you are mostly a gamer stick with the 8600K and spend your money on something cool like a NVMe m.2 disk

I think a lot of people over buy, when they purchase the 8700k.
