Model overview based on user reviews
The Intel Core i9 Skylake-X is a powerful gaming CPU that excels in high-performance tasks, particularly 4K gaming. Users appreciate its capability to unleash the full potential of high-end graphics cards, making it ideal for demanding applications. However, it requires a custom water cooling system and a compatible motherboard with socket LGA2066, which can significantly increase the overall setup cost. While some users note minor performance issues in basic applications like Word and Paint, the processor's 10 cores and 20 threads allow for multitasking, such as playing Dota and CS simultaneously. Despite its high price and additional requirements, it is recommended for those seeking a top-tier gaming experience.

Harvested 2 hectares of potatoes, if I had chosen AMD, I would have harvested 1 hectare of potatoes. Highly motivating. We all chipped in as a collective farm to buy this processor. Now I can’t scratch my balls while WoT is loading. With the old processors, I could afford that. just bought Intel Core i9 Skylake-X |
In work applications, I expected more. Switched from an old AMD processor to this one. Encountered critically high temperatures, went back to the AMD platform. Many cores and good performance in special offers, but the processor is excessively expensive considering competitors from AMD at half the price. It's possible that I had a defective processor, but its excessive temperatures even with a top-of-the-line water cooler really scared me, so I went back to my old AMD machine. use Intel i9-7980XE BOX less than month |
Now I play SAMP at 39 fps, whereas before it was 38... Witcher 3 no longer blows up the computer, now just the graphics card. There are some lags in Word after writing two words; The temperature starts to rise when I'm drawing in Paint; It lags in Minecraft with cheats.  Matthew Wersage: use Intel Core i9 Skylake-X more than year |
