Got this for a new gaming rig I was setting up. The first Amazon package came as an empty box. The CPU box had clearly been compromised at some point at the Amazon Warehouse (I'd have to assume) and it had no CPU inside, only the documentation. Amazon was quick to send me a new one, and it wasn't a huge setback since I was still awaiting the motherboard and case. Second package arrived just fine. You know what you're paying for here. This is a really high performance CPU with the capability to be overclocked to your heart's content, and (while nothing is "future-proof") it should stay relevant for a few years to come. Paired with a nice GPU (1070 GTX in my case) it's able to run literally anything I throw at it. Shadow of the Tomb Raider can run with nearly all settings maxed out/at high. It blasted through most stress tests I threw at it, and managed to score a 1456 on Cinebench's CPU test, hitting only 71 deg C at most. This CPU (obviously) comes with no dinky stock Intel cooler, so I'm using a Corsair H100i v2 for cooling here, and it pays off in BOUNDS. I can OC stable to 4.9GHz (what I have it running at now) and it runs cooler, both at idle and under load, than my last CPU did with its beefy Coolermaster heatsink/fan. Albeit, the radiator fans can get a bit noisy at times, but I've been tweaking my OC profiles to reduce noise and I've gotten the noise factor down a bit. Overall, I'm immensely satisfied. This is the first time (since the days of the 8800 GTX) that I've had a "relevant" gaming PC, something that can actually run modern AAA titles, and my quality of life has improved drastically as a result. No more FPS drops when I try and watch Twitch while playing Overwatch. No more stuttering and lagging when the OS decides to run some CPU-intensive garbage in the background while I'm gaming. It's pretty amazing. Here's the full build, for anyone interested. I wholeheartedly recommend this build to anyone looking to upgrade or build their first gaming PC, and it's relatively budget friendly compared to pre-built options, especially if you can snag some or all the parts on sale: Intel - Core i7-8700K 3.7 GHz 6-Core Processor Corsair - H100i v2 70.69 CFM Liquid CPU Cooler Asus - PRIME Z390-A ATX LGA1151 Motherboard Corsair - Vengeance LPX 16 GB (2 x 8 GB) DDR4-3000 Memory Kingston - A400 120 GB 2.5" Solid State Drive EVGA - GeForce GTX 1070 8 GB SC Gaming ACX 3.0 Video Card NZXT - H500 (White) ATX Mid Tower Case Corsair - 850 W 80+ Platinum Certified Fully-Modular ATX Power Supply Whole build totaled out to about $1,300 after mail-in rebates.

My second computer build i decided to build with Intel this time and it has been a much easier process to setup and overclock. I purchased the 8700K when it was new more than a year ago and have been using it since. Coming out of the box already running at 4.7GHZ on all cores is super impressive. I have always been a hound for speed so this makes it easy for me. Overclocking is a snap with Intel's easy overclocking utility that comes with alot of tools for stability testing as well. I tended to use Intels software for benchmark runs, and my Motherboard software for daily driving overclock. Now not every chip is the same and even if you have an 8700k, you may not see the same performance that i have been lucky to achieve. It's called the silicon lottery for a reason and I think I just got lucky. My Results are as such: highest Overclock achieved was 5.3 GHz on all cores. no problems and it worked just fine. For normal use i leave it at a nice and round 5 GHz and temps have not gone past 55c with a corsair AIO liquid cooler. So temps dont get hot, and it overclocks and is happy to sit there with no problem. I really dont know what else i could ask for since 6 cores/12 threads is more than enough for any workload i currently throw at it. In all gaming performance, i have not encountered any issues that are CPU related. Overall i couldnt be happier with my CPU. Pros: High Clock Speed Easy to overclock 12 Threads Cons: At time of writing is more expensive than a 9700K

The i7-8700K runs very well, I have 3 profiles where I overclock it to 4.2 GHz, 4.5 GHz, or 4.8 GHz according to my needs. The system will run at 4.9 GHz stably. Using the Cryorig CP7 thermal paste (9.3 W/mK) that was included with the cooling tower. Ambient temperature in my house is about 24 C. The CPU maintains temperatures of 33 C when idle & 40 C under load with air cooling on the 4.5 GHz profile which I use most. Even on the 4.8 GHz profile the temperature remains about the same on idle, but will go up to the mid 40s under load (42-45 C). I've ordered another cooler & will update in September or October when it releases/arrives. The system (built 2018) mainly for gaming with workstation, video editing, & streaming capabilities: Corsair Carbide Series Air 540 High Airflow ATX Cube Case with Corsair High Airflow AF140L fan x3 3 Noctua NF-F12 industrial PPC-2000 IP67 PWM 120 mm Fans ASUS ROG Strix Z370-E Gaming Z370 ATX Motherboard Intel Core i7-8700K @ 4.8 GHz on 1.25 V Cryorig R1 Universal Dual Tower CPU Heatsink with XF140 & Xt140 Fans ASUS ROG Strix GeForce GTX 1070 Ti 8GB GDDR5 Advanced Edition Carbon Fiber Graphics Card GPU Brace Support PCI Slot Bracket holding 2 Noctua NF-F12 industrial PPC-2000 IP67 PWM 120 mm Fans Corsair Dominator Platinum RGB 64GB (4x16GB) DDR4 3200MHz C16 on 1.29 V EVGA Supernova 850 P2 80+ Platinum ASUS BW-16D1HT Blu-ray burner Samsung 960 PRO NVMe M.2 512GB SSD addlink S70 2TB SSD NVMe PCIe 3x4 M.2 2280 Internal SSD Seagate FireCuda 2TB Solid State Hybrid Drive Performance SSHD Seagate BarraCuda Pro 10TB Internal Hard Drive Performance HDD DEMCiflex Dust Filter Kit Corsair Air 540 (8 Filters) Dell Gaming S2716DGR 27.0" Screen LED-Lit Monitor with G-SYNC Logitech C922x Pro Stream Webcam

I bought two 8700k's one from Newegg and one from Amazon.One overclocked to 4.8 stable in all games and editing but ran hot at around 75-85 @ a vcore around 1.2950. The other chip ran 4.8 at ease with 1.2450 vcore and 52-65 in games and editing.However I did delid and add liquid metal to both so I decided to bump the cool chip up a bit more to 5.0.I bought TWO of these chips just to try to run at 5.0Ghz 24/7 so I had to try.As happy as I can possibly be,the Amazon chip was the one from the better batch L805D729.Translation year 2018 week number 5 of 2018 that makes it the first week of February batch D grade from the 729th posistion of the waffer.I got it to boot at 5.4 with 1.4560vcore but was usless as it wouldnt bench anything.Same with 5.3 vcore 1.4560 would not bench mark.Disabled hyperthreading and bang, I could then run any benchmark I had at it but it was still no peace as it scored much lower with only 6 threads.5.2 however ran flawless at vcore 1.4350 but it didnt like it cause the temps were staring down a 90c max temp.So I relaxed it back at 5.0 with a vcore of 1.3250 and LLC set to 5 and maximum cpu current to 140% with a H150i RGB Pro(360mm Radiator) and its fans set to 100% duty cycle by 65c it never goes over 67 and it seems to enjoy its self.The whole reason I bought two was so I could find a trusty 5Ghz chip.So since I got a hot chip from Newegg I decided to try my luck with Amazon to possibly get a better batch from them.It worked.I had a i7920 overclocked to 3.7Ghz for 8 years and tested my new 8700k against its benchmarks I had saved over the 8 years and wow the 8700k is like 6 i7920's combined, maybe more.Very happy to have yet another i7 flagship future proof monster.My i7920 rig was bottlenecking the hell out of my GTX 780 as well.Now that I have an actual PciE3.0 capable motherboard, and a chip that can exploit it's bandwidth and gpu calculations its performing like a brand new experience.GTX780 now performs at least 30% better or more no exaggeration I thought it was time for a new GPU at one point then I realized my i7920 was a total bottleneck glad I upgraded to the 8700k.

Bought this on Oct 6., was finally delivered on Nov. 5. I had been buying parts since July and really was excited once I knew it had shipped so I was ready to do the mods I wanted to before turning on the first time. With the CPU out of its box and ready for action, I immediately delidded with Rock-It kit. Cleaned off Intel's TIM and replaced with Phobya liquid metal. Resealed with Rock-It kit and black RTV leaving the extra spot for heat expansion that you'll see once you delid. Let dry overnight and NOW came the time to build exactly just one month after ordering. Placed an ASRock Fatal1ty Z370 Gaming K6 into a very nice Phanteks Enthoo Evolv ATX Glass (I have bought Phanteks for my last two builds and this case has impressed me beyond what I could have expected). Next, I placed the CPU into the board and installed a Kraken x62 (with replaced fans using 4, Corsair ML140 in push/pull) for cooling. I decided to go with Thermal Grizzly Kyronaut between the 8700K and the x62 . Of course, at this point I wanted to boot to see how things looked temp wise but the rest of the build remained and at least we all know some fun was still to be had. So, off to installing a Samsung 960 M.2 for Windows and two Crucial BX300 - 480GB in RAID 0 for games along with a Seagate 4TB for bulk storage. An EVGA 1000 SuperNOVA G3 80Plus Gold went in for power as it would need to help deliver power to all these goodies along with an ASUS ROG STRIX GTX 1080Ti 11GB Gaming for Battlefield1 ... CoD4, DiRT 4, GTAV, and some of my other recent favorites. My RAM choice was the G.Skill Trident RGB 32GB 3600.G.Skill 3600 and they slid in without issue. First boot finally!!!! Into the BIOS I dived to check temps and set up the RAID and memory XMP. With the Kraken I was idling at 26, so I set up the RAID and went on to install windows/drivers/updates along with all the CAM software for the Kraken and NZXT Fans. A quick reboot just to make sure everything was nice and smooth, which it was (phew), so one more reboot into BIOS to try for a pretty aggressive first OC. I pushed the 8700K to 5.1 GHz and pushed the G.Skill to 4133. Save changes, reboot, palms sweaty hoping I had maybe got a little lucky in the silicon lottery and would end up with a nice fast and quiet machine. SUCCESS, as I easily went Into windows. Launched Prime95, full Torture Test with MAX LOAD... temperatures of... 62C!!!!! Same temperatures were seen in Heaven as I played with the OC on the 1080 and even saw a 1 degree drop with some linpack testing. Looking at other reviews, it looks like delidding worked for me in this setup and I am glad I did it. Because of the temps, the fans on the Kraken are barely audible along with the other case fans. Needless to say, this thing hums along nicely at 5.1 GHz with the RAM at 4133. Gaming is an absolute joy and day-to-day operations move with ease and fluidity. I am very happy with this CPU among all the other goodies and highly recommend it. If you decide to delid it, I wish you luck (just take your time) and great temp reduction.

Quite good, one of the best for games currently. Top 3 right now are 8700k, 9700k and 9900k, and you can include 8086k (if you can find it), but it will be around $600, and who wants that when you got 9900k for ~$510 I had 8700k fail on me, so I replaced it with 9700k, 8700k was hotter, but needed less voltage if you were to set it at 4.7 ghz, on 9700k I can't even keep CPU stable at 1.3volts for 4.7, on 8700k I could at 1.21 volts. Feel the difference? Thermals are better on 9700k, with same cooling, if comparing to 8700k. It is slightly faster in games then 8700k, but slightly slower anywhere else while using PC. If you are choosing between the two you can't go wrong with either, but mine cannot even keep stock settings without crashing games. 8700k ran stable, needed less voltage too, so it was cooler because of less volts. I didn't feel like overclocking 8700k to 5.0, I kept it nice and cool. I can't downclock 9700k to anything in comparison. So I kept it stock, but it kept crashing in AIDA 64 with hardware failure message. Also getting bluescreens, etc. I do believe I got a bad chip/bad silicone this round, so I am returning this, and bought 9900k as a replacement. If you get a good 9700k chip, you will get better gaming experience than 8700k. If you stream and do rendering get 8700k, but in Adobe Premiere 9700k is better, because it has real cores, and not threads, so in other words both are good, but neither is better than another. The best for gaming now is 9900k, but you need better cooling. 8700k was quiet hot, and needed more cooling in comparing to 9700k. Hope that helps you choose. As long as you get good chip 8700k/9700k will be perfectly fine. I like 8700k better because it was snappier altogether, but 9700k was better in games. So yeah...both good But leaving 4 stars due to getting bad chip, it could have been higher, but I am not gambling with my time no more. 9700k is soldered, 8700k is not soldered, so this is why 9700k is cooler. Keep that in mind.
