It is now not the fastest but it still is a viable and great CPU

Not sure why all the confusion because of so many of the reviews are about the 4790 on the 5820K reviews. I have owned the Intel 5820K for about a year and I air cool with a Noctua NH-D15S with two Noctua fans. It runs cool at 35C. I use it for my camera shots and videos. It was at one time one of the best CPU's for video editing and overall computing. While supposedly not a great CPU for gaming, I can say it does an excellent job of preventing CPU bottle neck. I had previously an AMD 8350 overclocked to 4.9 Ghz. and even with that speed it would often slow down and stop with the computer locking up. With the 5820K, I have never had any computer locking up problems when editing videos. I never had problems, period. Now as of August 15, 2017, the Intel 5820K is no longer being made but there are a lot still available at excellent prices. With the pressure from AMD and their Ryzen and Threadripper, older Intel CPU's which at one time was the best of the best, can be bought often times at half the price of their original price. The 5820K is still a viable CPU for most people and for many years to come. How many cores and threads do you need or are enough? The big thing today seems to be core and threads. In the past, it was how fast......I remember when 1Ghz was thought of as impossible. Now it is core count. Marketing? Funny in a strange way that software for the most part cannot use 16 cores and 32 threads. Sure they test great in tests but tests are not the real world. The 5820K is still a great CPU and will be for many years to come. The bottleneck now is software and using even the 6 cores and 12 threads that the 5820k offers. Don't fall for the marketing.....more cores often means for the average computer user more cores sitting there idle while they do nothing. I highly recommend the 5820K. It is a good deal now and the motherboards are now less expensive than they were when they first came out.Read full review
