If you are a fan of the blue company and can buy this processor on finance, then okay
27 April 2021 
Not recommended for purchase due to its price and terrible power consumption with expensive motherboards, and also buy at least a 700-watt power supply if you are going to overclock the CPU. I used to have an i7 7700k and decided to upgrade. Expected more, but got less. It's better to go for an i9 10900K, which will consume less and be more productive in multithreading or almost.
Support for PCIe 4.0 lanes
New DDR controller up to 3200MHz
New integrated graphics card UHD 750
High energy consumption
Price/Performance
Overclocking is not high compared to the 10th generation (Maybe I have a bad unit)
Good cooling is required
Not recommended for complex CPU-demanding tasks
Expensive motherboards for CPU
use Intel i9-11900K OEM less than month
