The Central Processing Unit (CPU) or (micro) processor is the part of a computer where most calculations take place. In terms of computing power, the processor is the most important element of a computer system, so the performance of a computer is highly dependant on the performance of the processor. For quite some time the performance of a processor has been determined by the number of MHz the clock speed was, but nowadays clock speed doesn’t have so much to do with the speed of the processor anymore. Please be careful to buy a processor that is compatible with your motherboard, i.e. fits in the right socket.

After 6+ years I finally decided to upgrade from my i7-7740 to the i7-9800x. Ran it through numerous stress tests and it works great, I can definitely tell the difference when in VR!

It was more that I expected. Used a single-edged razor blade to clean off the thermal paste, dropped it into the LGA, applied new thermal paste, and installed the Noctua heat sink.

I have not installed it yet.
No cooler means that I save money on something I do not need. Works wonderfully in my new ASUS Prime X299-A II LGA 2066 Intel X299 SATA 6Gb/s ATX Intel Motherboard.
