Works fine, lasts a long time, a good prices and delivery was quick. I'm a happy camper.
It works as advertised, it gave me 35+% improvement in performance over the i5-4670 CPU that was in my desktop unit. A side effect of doing the swap was a discovery that the original CPU cooler was not seated properly. In the process of correcting that issue I also upgraded the CPU cooler. Now things are faster and cooler. Video rendering is much quicker. The new CPU was an inexpensive but significant upgrade path. Owners of functioning older desktop units might want to consider that path if their budget is stressed. One caveat, make sure that upgrade CPU is of the same design and socket family. The i7-4790K is a Haswell 22nm technology, using a socket 1150. The i5-4670 originally in my desktop is the same technology and socket 1150. The same socket type is an absolute physical requirement. A different technology will need a BIOS upgrade to the motherboard to work, which is quite problematic for a host of reasons.Read full review...

I7 4790K
Definitely a performance increase, when compared to an Intel i5 4690K. But not exactly breaking records here. seem to handle occasional gaming as well as all other applications, such as photoshop, video editing, and music recording. Haven't tried to overclock yet.
Overall a good upgrade. Read full review...

Amazing CPU
For a 4th gen intel, this cpu is still relevant today. Haswell definitely has its cons, but the pros outweigh it. I've got mine clocked at 4.5ghz with a cooler master ML120 keeping it cool at around 35-40°c. Paired with my GTX 1080 FTW2, it destroys any game in any res. Some 4k games are a bit much still, but regardless, this cpu is definitely worth picking up. Stock clock of 4ghz and turbo to 4.4ghz, this thing is a beast. Strongly recommend picking up if you've got the cash to spend. Although I would also recommend looking for deals. $250 is still a steep price for a 4th gen, when the 7700k is only 50 bucks more. I would say 180 or less would be a great value for the money. Pick one up today if you're still running 1150 haswell!Read full review...

Replaced 4690K with 4790K
Got this 4790k used for a decent price. Upgraded from 4690k since my 1080ti was being bottlenecked in some games. Right away was not happy with extreme temperatures on this 4790k compared to my 4690k. This one got to 90C on stock under my custom water loop. I figured since this was used, Intel's TIM dried up. I de-lidded and re-lidded with CL Liquid Pro. Temperatures dropped by 20C under load. Somewhat frustrated I needed to delid even to run this thing, thanks Intel TIM. Besides that, performance is solid. Can't really reach 4.7 without an unreasonable amount of voltage(same with my 4690k). My 4690k at 4.5GHz outperforms it at 4.5GHz in single and quad core performance. Multi threaded in 4790k of course is performs great. Certain games which were CPU intensive have benefited greatly, other games not so much. Overall I'm happy with the performance despite the fact I had to void the warranty to get temperatures under control!Read full review...

Good chip.
I love these chips. Unlocked (-k suffix indicates that) multiplier, and stomping singlethreaded performance.
Clocks comfortably to 5.1ghz on water cooling (custom loop), and benchmarks are amazing.
That said, I have indeed burned one up after like 4 years of severe abuse in a heavily clocked system, and that's the first chip I've ruined in a long long time through abuse rather than mishandling or having a cooling pump/fan failure.
That said, the one issue that i've had with mine (both of them) is that they have zero thermal inertia--the temps can swing from 30 to 70C in a heartbeat, which suggests that the thermal interface material under the heatspreader (the lid, as it were) is kinda craptacular. I'm sure I should go through and delid it and replace it with something fancy, but if I only blow one up every few years, I can live with that. I'm of the mindset that you ignore temperature and pay attention to crashing and data corruption. Hot? Who cares :D

If you're LGA-1150 motherboard supports it, go 4790K
I had a 4770k that died and I needed a new processor. I got the 4790k. This processor runs at 4.0GHz stock and boosts to 4.4GHz without any overclocking. It works well and consistently (for the week or so that I have used it.)
Using a GTX 1080, I am playing Destiny 2 and Assasin's Creed Origins origin at 1080p 60FPS with no problem at all. The processor is fast, and easy to install, but there is a possible problem: My motherboard does support the CPU, but I had to upgrade the management engine and BIOS before I put in the new processor. Before I did this, the board did not recognize the processor and would not post. This is *not* a CPU problem, but an older motherboard problem.
It now runs flawlessly, and i don't think I will even overclock it. It runs just fine as is.
So, If you have a Haswell motherboard with plenty of ram, and want to squeak by for another year or two, try the 4790k. Read full review...

Works great and a very good upgrade
Working as expected, and a worthy upgrade to the G3258 processor that was previously in my lower budget HTPC system. Having 4 cores is great and also clocks down and runs cool when idling. It doesn't have to be cutting edge, but the upgraded system will be good for a long time to come, without transcoding bottlenecks. Could have used the much cheaper 4790 (non K version), but might as well be able to overclock in the future.Read full review...

Great processor
I have an Asus Z97-AR motherboard with an Intel i3 processor. I didn't feel like spending the money upgrading the motherboard and the required hardware, so I figured I'd upgrade the processor for extra speed. I decided on the coveted i7-4790K, and found a great deal on ebay. It performs better than I ever thought, and it will allow me to keep my current PC setup for a few more years.
As a side note, I also upgraded the heatsink/fan to a Cooler Master Hyper 212 EVO V.2, combined with Noctua NT-H2 thermal paste for incredible cooling. Read full review...

Just the ticket to extend the life of your LGA-1150 Machine.
if you are trying to stretch out the life of your intel 1150 socket, this cpu is the baddest you can get (assuming you are upgrading from a haswell cpu). The cpu will ramp up to 4.4 ghz in turbo mode, and stay there as long as you have a decent cooler.
I upgraded from a haswell 4560 cpu, and needed a bios flash on my motherboard to be able to support this. so check your documentation, and make sure you are running the latest bios. Some Asus boards (like my Z87k) have a very specific method to bios flashing that requires specific (older) intel chipset drivers and MUST be flashed with the bios updater program IN WINDOWS. So keep that in mind if you have an asus board, and do your research. but after the headache, this thing runs great, and made a noticeable boost over my i5.Read full review...

Not much else to say
It's the fastest ddr3 cpu ever made, and there isn't really much else to it. Is it worth picking up in 2018? Well, the closest modern equivalent to this processor is the i5-8400, which scores almost identically overall on passmark and gets very similar results of the 4790k on various benchmarks, with a slight edge to the 4790k in most single core tests and a slight edge to the 8400 in multi-core tests. By slight edge I mean a +/- 5% difference. 2 extra cores, newer revisions of various features including turbo boost, ddr4 memory, and 4 generations of architectural improvements and several transistor shrinks weren't enough to bring Intel's newest mid-range offering ahead of this aging flagship.
If you are still sporting a Haswell i3 or locked i5, the i7-4790k offers a substantial gain in performance, and should seriously be considered with the RAM market being as it is. It could comfortably be paired with a 1080 ti and play any of the newest games, and for productivity you aren't going to do better for your money if you're sitting on a lower end haswell system already. Even if you just had a good amount of ddr3 lying around and wanted to build a cheaper used system from scratch, the 4790k should be near the top of your considerations.
There is little sense in paying full retail price for this chip, as they are built like tanks and there is little risk in purchasing them used.Read full review...

Fastest LGA 1150 CPU you can get
Cons:
Runs hot, use a good cooler.
A bit expensive, There are older 6 core extreme processors that perform better on workloads for cheaper used. (3960X on X79 Platform)
Pros:
Can handle its Turbo speed 24/7 without any adjustments.
Fast for gaming and multimedia
Great single core performance, not far behind a 6600K
Not a huge TDP for how fast it is
Power efficientRead full review...
