Intel Core i7-7700K 4.2 GHz QuadCore 8 MB Cache CPU - Black

Blistering speed - for my first time ever the CPU got a higher score than GPU (RX480) in 3D Mark (Time Spy test). Intel makes really good processors, I'm utterly amazed how they fit four cores *and* a very decent GPU into this tiny processor with such reliability and performance. It's quite expensive but there are features that justify the price for me: 1. Build in Graphics processor is very decent - it handles all web browser graphics and video, and can drive multiple screens. If you do not need the sort of power to play top end games, you will not need to buy a separate graphics card. 2. It's designed to be overclocked - I'll reserve that for the future. At the moment it doesn't need any improvement from the factory settings; but in 5 years' time, who knows? It will help it keep up with newer models, therefore increasing its longevity. It arrives factory sealed with permanent tape over the box flap. Intel does not spend its money on packaging but it's adequately protected. You need a cooler to go with it, I'm using Cooler Master Hyper TX3i. As usual, pins are on the motherboard, not the CPU, and installation is easy - but also very scary, considering the price. The trickiest part is after installation - attaching the heat sink and stressing over the perfect paste application. Temperatures are around 35℃ most of the time, 40-45℃ during 3D Mark GPU tests and 80℃ during CPU test. As mentioned, I have never had a CPU that blasted through the 3D Mark tests like this - Time Spy CPU test starts at 60 FPS, and finishes at 18FPS without overclocking.

I have upgraded from an i5 7600k wich was 100% load in games like Battlefield 1 . I did heard about the overheating problems that i7 7700k processors have , but I believe it's only luck that keeps you from getting a good processor . In my case , the first one was heating up bad , even on watercooling on an expensive system. so I decided to speak to amazon to see if I can get another one as a replacement .they were helpful as always and they understood my problem . I just installed the replacement and I must say it is a big improvement . The first one was getting up to 90c max temp , while this one stays at around 70c max. on the exact same system and cooling . Thanks to amazon's great customer service I was able to get the performance I was after for the top money I paid . great processor if you game a lot like me , and future proof also .

From what Ive seen so far. Beast of a gaming CPU and that's all I use this rig for. I don't stream or do any 4k (or otherwise) rendering with it. I have an X99 rig for that if needed but that's being used by the other half at the mo. Temps run hotter than I'm use too with the X99 5820k. The H80 V2 was what I used with the 5820k and then for a short while with the 7700k. I've bought a Kraken x62 which is a cracking bit of kit and keeps the temps around 49-54c on load @ 4.5GHz in ghost recon wildlands. I'll be overclocking it up to 5ghz when I get a bit of free time. Paired the 7700k with an Asus Apex using Trident Z memory. To be honest the FPS is better slightly at the highs but the minimums are way better and stable for the games I use. I hope this helps someone!

If your thinking of buying an i5-7600k, just save up and buy the i7-7700k. That's what I was told and did and couldn't be happier with my purchase. Fast and powerful proccessing power and next best thing if you cant afford i7-8700k. Plus if you think you need a liqued cooler for it you don't because the cooler master hype evo 212 is enough for it for gaming atleast on the i7-7700k. Temps stay between 45-55 degrees Celsius when under load of games like the witcher 3: wild hunt. If your not happy with that I think it's ok to add another fan onto the other side of the hyper evo to have a push and pull configuration just research it to make sure otherwise get a 240mm liquid cooler it's expensive but efficient. If you also do plan on doing a lot of overclocking at high speeds where the voltage go's up significantly I recommend going with a 240mm liquid cooler.

Intel Core I7-7700K is fast, fluid and great for multi tasking on high end PCs alongside a powerful gpu such as an GTX 1060 or beyond. Didn't keep it for long because I thought I had damaged the underside of mine with thermal paste, turns out I didn't and was sent back for nothing, error on my part. My only gripe with these modern CPUs is how small and easily damaged they can get if handled incorrectly. The old big chunky ones were near impossible to break they were that strong lol. Compact and light though, get this if you can for a gaming PC build.

As all CPUs are unique, I can only speak for mine, but I received an amazing overclocker! It reached 5.2Ghz easily on my Asus Prime Z270-A motherboard. I even got Windows to boot at 5.3Ghz, but heat was becoming an issue, so I backed it down to 5.2Ghz, and 5.1Ghz for 24/7 clocks. At the end of the day, it's an i7 7700K, a pretty iterative update to the 6th generation Skylake, so you should know what to expect here. I was upgrading from an Ivybridge 3770K system, so there was still a decent leap forward there for me going from 3770K to 7700K, especially on the chipset side of things with the jump from Z77 to Z270, but if you're on a Skylake system, It will certainly be a small step forward. From my point of view though, it's an easy five stars!

The first thing you realise is that it runs hot. And I mean HOT. If you intend on using it for gaming then you *must* pair it with either a serious cooler (e.g. Noctua NH-D15S) or preferably water cooling. If you intend on overclocking then at a minimum you need a high end water-cooled system. Even then there are multiple reports of excess temperatures. Personally I don't game on my PC and use relatively undemanding illustration software. Even so, with default set-up and an ambient temperature of 21 - 23C I was seeing idle temps of 41C and load temps of 82C. Using the Prime 95 stress tester, just for a laugh, pushed it up to 100C within 10 minutes. I am running with a Noctua NH-L9i cooler which should be sufficient for the kind of work I want, but under default settings is not. And that's not the fault of the cooler. The solution in my case was first adjust the CPU fan profile in the BIOS. Noctua fans are very quiet so this wasn't a big deal and making relatively small adjustments brought down the idle temps to 37C. However it didn't have much effect on the load temps (as the fan already ran at full whack under load) and this was only addressed by disabling the Intel Turbo Boost in BIOS, essentially reducing the clock speed from 4.5 Ghz (the default out-of-the-box setting) to 4.2 Ghz. This brought the temps down to 33C idle and 67C under load, which is fine. Just for comparison, I ran Prime 95 on my old PC with its 6 year old i7-3770 which idles at 28C. Maximum temps were 59C. And that's with a basic £25 cooler. After researching the details you find that the i7-7700K overheats so much because Intel, in their efforts to save pennies, use low quality thermal interface material (TIM). This is the paste under the CPU lid, not the paste you apply between the heat spreader and the cooler. People have replaced the TIM (requiring a process called delidding) and experienced temperature drops of 30C. This is insane. For the sake of probably 20p per CPU, Intel have pushed out a chip so compromised it can barely perform the function for which it was intended. Whilst it's true that the performance difference between 4.2 Ghz and 4.5 Ghz is minimal (and not noticeable for my own use), it's absurd that I am compelled to either do this or pay a fortune for a cooler the size of my head. This brings me on to the speed of the CPU in general. Meh. My old PC utilises a 6 year old i7-3770 and there is little difference between that and the i7-7700K. At best the 7700K is 20% faster. All in all a very underwhelming experience. If you're a gamer or video editor you will absolutely need a high end cooling solution for this chip, and even then take care when overclocking. If you're not a gamer then I'd consider not buying this CPU at all, as I honestly can't see the advantage. Maybe consider the cheaper 6700K, which is essentially just as fast, the 7700 or a Ryzen (although I've not researched Ryzen so I don't know much about them).

Amazing little chip I did previously own the 7600K whilst plenty for gaming I ventured on to the i7 7700K to replace it to ensure that my system stays on par with my 1070 in my rig whilst playing gta v and battlefield 1 (known to be CPU heavy) on the 7600K cpu usage was at 100% now with this chip it barely goes upto 50% the £100 extra may not seem worth it for some but for me was definately a smart choice as GPU's will only get more powerful and so the 7600k would eventually bottleneck my advice by this CPU to be truely future proof also has much better overclocking potential compared to the i5 would also reccomend a water cooling option for best overclocking
