Why would I get an i7-6700k vs a 4790k or 5820k?

It seems to me they both out-perform the 6700, unless I'm mistaken???

What are your thoughts and opinions and facts? Please share.

I have an AMD FX9590 (OC'd 5GHz & undervolted @ 1.45v) R9 Fury X build and now I want to build an Intel powered beast.

What would be the best Intel CPU to build a gaming monster?

well the 6700K is better at some specific tasks, but for gaming, the 4790K is cheaper and the same, and the worst for gaming would be the 5820K simply due to its lower stock speeds. for gaming get the 4790K ( and OC it! for more raw power) and a good watercooler. ( you probably already have one for your 9590) the 5820K is not worthwhile unless you can justify needing 6 cores. 8 threads is plenty.

The 5820k does have access to 28 pcie lanes so if you wanted to run a multi GPU setup it would have an edge. The 6700k is a Skylake CPU giving you a better upgrade path in future. However really for a gaming system the 4790k is still a great CPU.

the thing i remember is that the 6700k had and edge on games like project cars(not sure if it was that game don't really remember)
it gained like 15 more frames (the review was at dark side of gaming i think) while the advantage is there its not really worth it if its still priced at 400$ or more if it was priced at 350$ or less then its worth a shot

I am not a big fan of SLI or CrossFire. I've never really had a good experience with it. In my AMD build I switched from 2 R9 380s to the Fury X because every game I played had flashing textures. Tried everything to make it work.

Choosing between these Intel CPUs is a bit of a hard choice. A socket with a future upgrade path is definitely worth it, at the same time there's a lot of praise for the 4790k.

I'm narrowing it down to 6700k or 4790k.
Will be using single GPU (either Titan X or 980Ti). Requirement: Day Z and Arma 3 playable lol

Thank you for the quick responses and keep the opinions coming. We will get to the bottom of this dilemma eventually.

6700K for the later technology and DDR4. 4790K is not better in anyway, only cheaper and no upgrade path down the road. 6700K is slightly faster (by a hair) and will still have options of upgrades later on. My opinion 6700K>4790K

Use the price savings for fast DDR3 and a better motherboard =- better performance over all. the 6700K is a great chip, but unless you have applications that need one of its specialties, there is not much reason to have it other than staying current. look at the people with their sandy bridge CPUs, they are not complaining, they just up their clocks.

and haswell is not propitiatory as issuefull skylake is -Microsoft trying to block anything but 10 use on it -- limited cpu support /no xeon on 100 series - coolers damaging skylake chips one of the most viewed threads is the skylake freezing one .. so on ..... ol'skylake don't look all that good to me overall - poor old haswell tried and true and proven to work [opinion]

'Best' is a judgement call. For gaming, you need a great GPU (you have one) and a CPU to drive it. The i7 6700K has the highest IPC (by about 5% over the i7 4790K). For me that 5% means nothing much, and may be nothing at all when I run an i7 4790K on 2400Mhz memory, which I do. (I have yet to compare with Skylake on fast memory too)

The i7 5820K is the most powerful (with the greatest throughput) in applications that can use all six cores. (Other than gaming)

As a personal choice, I am rarely an early adopter in technology. I like to wait for the bugs to be ironed out. (or Rev 2.0 to be released)

I'm still happy recommending the 4790K. Dead socket does not matter. Top end CPU socket upgrades are an idea that very rarely happens. Skylake i3 to Kaby Lake i7, I can see. Skylake i7 6700K to Kaby Lake i7 7700K isn't going to happen from choice.

haswell [ find a board you may like and then go to its support page and check the cpu list and what bios its supported under]

https://pcpartpicker.com/parts/motherboard/#s=24&c=99

do the same for the skylake

as far as whats best ? that comes down to user experience and personal preferences

we could tell you all day whats the best and you find out for that for ''YOU'' its a hunk of junk

i upgraded from fx 8320 to i7 6700k, big jump of performance. no regrets.

Memory perfomance is easy to compare. (its not all about memory clock speed)

(1 / (Clock/1000)) * CL = nanoseconds (delay per cycle)
Ex:
Hyper X Savage DDR4 2400mhz CL 12
(1 / (2400/1000)) * 12 = 5ns

Have the same performance as

Corsair Dominator DDR3 3200mhz CL 16
(1 / (3200/1000)) * 16 = 5ns

In my country this DDR4 model is cheaper than Corsair Dominator 3200mhz.
Here we can found all this processors for the same price, if you can too, go for 6700k due to futureproof.

well just looked at my last post and this part did not get added ??

a lot of motherboards you don't know what bios is shipped on them from the factory my rule is all ways count on it being the first release bios

lot of guys get boards with chips that require a later release bios and now cant post cause its not a compatible bios for there chip

example ....

you get a board that has a first release bios on it say bios 1.00 but the chip you order to use needs bios 3.50 - with that you may not be able to post and then you would need a cpu that works under the first release bios 1.00 in order to flash to the bios you need for the chip requiring the 3.50 bios

get it ??? so it can be important to look at that

Something like a Gigabyte Z97X Gaming 5 would be a good motherboard for overclocking, gaming, and all- around goodness at a moderate price.
