I initially bought the I7 11700k for my build. I have a 9 year old who all of a sudden became very interested in computer gaming and needless to say I needed to build another rig if I ever planned on using my computer again. I ended up going with an upgrade on the CPU and went for this chip. So far I haven't had any issues I haven't really noticed much of a change but I also haven't put it through it's paces yet either. I'm currently running it on an Asus z-590e with 64gb of ddr4 3600, and a EVGA rtx 3060ti.

Excellent performance on par if not better than my 5800x which is a golden sample with both running on EVGA 360mm AIOs. 11900k runs much hotter and draws much more power to do it, but it does it and that's what matters. Expect pulls of up to 300w+ using Intel ABT mode and heavy workloads as Intel ABT mode defaults to ~1.45v. An AIO is pretty much required or at worst a cooler ambient case with a Noctua NH-D15 at the minimum or accept running at stock (or lower) speeds when running heavy multi threaded workloads.
During gaming sessions, temps never hit 70 and stayed in the low to mid 60's even in Intel ABT mode (5.1 multi / 5.3 single).
I was pretty happy with my 11900k but.....
Unfortunately my CPU died. While playing WoW, system suddenly shut off. Went to power back on and red light on MSI Z590 motherboard indicated CPU error. Usually it is the motherboard, but I was able to test with other parts on hand. Swapped in an 11400 and it booted right up. Tried the 11900k on an Asus B560 Prime (used for the 11400), same CPU error.
Pity, but I'd still recommend an 11900k if you want the absolute best 8 core / 16 thread performance and you have the VRMs and cooling to support at a minimum Intel ABT mode or greater depending on silicon quality.

Not sure how the reviews have been bad on this cpu... I love it! I swapped out a 10850k running at 5.1 for this. I'm running 5.2 all core with 5.4 single core boost and 5.3 quad core boost. I jumped 10fps at 4k in horizon zero dawn. Only game I really tested. This also opened an nvme port so I added a 980 pro and cut game load times down 30% or more.

I mean it’s a serious processor, It’s a beast. Keeps cool under heavy load with my z73. Literally handled most everything I threw at it from benchmarks tests and heavy load tests. Gaming is too easy so long as you have a card to support it.

Great CPU. This CPU is an upgrade from the i7-11700K for me. Bought this at a great price since Best Buy Priced matched it from Amazon for me!! Saved over $200. Not much of an upgrade i realize but this CPU is no longer being made and wanted to make sure i had a spare just in case =).

Upgrade from Intel I3-10100 to I9-900k

This upgrade was well worth the money. Once I upgraded my GPU to RTX-3080ti FTW3 Ultra I thought the i3 was a bottleneck. After upgrading to the I9-900k I'm seeing gaming frame rate increases of 40-55 frames or more. Solid gen 11 cpu even with 8 cores and a great price from Best Buy.

If you are looking for a good LGA 1200 processor, look no further. Despite negative reviews at launch and even to this day, this processor is a solid choice for gamers. I play AAA games such as MWII and average 125 FPS, which isn’t a high end FPS count, but adequate for a casual gamer.
The chip idles at 25-29 C and 65-75 when playing games and using multiple programs.
Overall solid chip.

After installing this in my MSI MEG Z590 ACE to replace a core i7 10700k, my system was noticeably faster. I'd say it was about a 20% overall increase in speed because the new processor was taking advantage of PCI Express 4 for my SSD and RTX 3070 graphics card. I was shocked to find out that I got a lemon though.
Not long after installing it and playing a few games to see the difference in frame rate, I decided to really put it through it's paces and do some benchmarking with 3DMark. At the end of one of the tests, windows bluescreened. I made sure to check that my BIOS was on the latest version and I also reset it to the default settings. At this point, it didn't take long for windows to throw up more bluescreens after launching 3DMark again. The error codes were also different on each screen, indicating that something is defective.
I took the 11900k out and put my 10700k back in and it has been running fine ever since. Looks like I'll have to exchange it for a new one as I really did like the increased performance it provides.

You might wonder why I bought this instead of investing in 12900k or 12700k or anything like that since 11th gen has a very bad repo from tech community overall... in my case, I built a PC on 2020 and I had bought a 1900 (non k) version. I mainly use it for work and gaming. No major multi-thread use case for me. I invested in a very nice z490 top of the line back then MEG ACE. As we stand here now, there were following paths - continue to use the 10900 on such a great over clocking board, get a 10900K or invest in z690, ddr5, 12th gen processor etc. My goal is to use the z490 platform for another two years or so. Hence, I decided to update to 11900k as it is at a massive discount as of today. It gives me pcie gen 4 support (since MEG ACE supported it) and offers a 19% IPC uplift compared to 10900k. This CPU also support DDR$ speeds in excess of 5GHZ out of the box. The replacement was smooth and had no issues.
