I know the "k" stands for unlocked, and I don't really plan on overclocking (Maybe I will, although I doubt it a lot). But the i7 8700k has much higher clock speeds and MHz, does it really matter? Will it make a huge difference in gaming and 3D modelling? Also, I plan on getting the Gigabyte Z370 Aorus Gaming 7, wether I overclock or no, I love that board, is it still recommended for the i7 8700?

So if I have the budget to get the 8700k, you would recommend me to get it right? As you say, atleast I have to option to overclock. And one quick question, can I slightly overclock on a Corsair H80i v2?

Im very pleased with my 8700 (non K), if you dont overclock the difference is nominal as RL stated above. Id stick with the non-k and put extra $$ saved into gpu or ram :) Go ahead and put a good aftermarket CPU cooler on there as the stock cooler slightly diminishes performance at high demand loads in some cases.

If you want to keep that option open, overclocking, be sure to buy a Z370 motherboard, one that can overclock your CPU when you want to do it. Other 370 boards, such as the B370 and H370, do not support overclocking.

That's a great CPU, but the 8700k itself it's quite expensive, the 8086k is even more expensive.

The stock cooler on an 8700 is fine, youd need really poor case airflow for it to be an issue. That CPU doesn't throttle until 90 deg C, if your cpu is running that hot you have major case cooling issues.

The 8086k is simply a golden sample 8700k, they are identical except the single core turbo is 5ghz instead of 4.7 ghz. Its not really worth the money, unless you are overclocking and want to make sure you are starting with the best possible chip.

Toms themselves just did a review that said the stock cooler is totally inadequate on the 8700, on an open test bench.

The turbo boost clock (multi-core) more or less negates the difference between the 8700 and 8700k IF you can keep the thing cool and don't plan on overclocking anyway. In the past, the difference between say the 7700 and 7700k had much bigger clockspeed differences, both base clock and turbo boost clocks. That is no longer the case. The lower base clock on the 8700 is just to make it fit the 65w TDP.

Im currently using a Corsair H80i V2, and I love it, so ill keep it for the 8700k. And not really, I dont want to overclock that much to get the 8086k, maybe just casual OC or even not OCing at all.

I am using a Corsair H105 with my i7-8700k in a good airflow case (TT V71) and my temps even while gaming never gets over 55c.

I'm not overclocking either, though I could with my Z370 motherboard. The reason is the automatic boost clock works just fine to boost the CPU when it needs it.

I'm past the days of trying to live on the wire, on the edge - I'd rather just have fun with my pc and not worry about little details all the time. The i7-8700k is good at allowing that. Not sure I would spend the extra for the i7-8086k to get that higher boost - it's about $80 more to save perhaps a tenth of a second in time opening an application. Not worth it to me.

I have that one and in my opinion getting that one and not overclocking is a waste.

Reason: in reality both 8700K and 8086K have the same boost table apart from one thing - 8086K is allowed to boost to 5GHz single core, but reality is - that never really happens, so if not OCed you get exactly same performance like 8700K. When OCed - 8086K seems to have better silicon overall, so it can be pushed higher, but in any case you will need to delid to achieve decent and stable OC.

As for 8700 non-K, it is actually very close to 8700K when turbo boost is going (which is always if you have at least some decent cooling - not the stock terrible fan they include), so if you do not want to OC - 8700 makes a lot of sense. Base clock seems low, but you will never be there if you have decent air or liquid cooling.

As for cooling - good air cooler > budget liquid one. IMO any liquid cooler below 100 bucks is a waste of time, because it will be outright worse than any premium air cooler 20-30 bucks off that price.
