A BEAST of a cpu 8/10/2020 1:38:04 PM

Pros: cheap for the performance
runs cool with the right clock and voltage (35c at idle- 55 while gaming) with cheap aftermarket cooler.
runs all my games smoothly
stable and easy to oc

Cons: really hot with stock clock speed and voltage

Overall Review: Great for almost all purposes, especial for gaming as it can run all games with ease. I had to put it at 4.2 ghz with 1.25 voltage to get the most out of it while being cool.

Upgraded from 1700X 8/10/2020 10:48:06 AM

Pros: - Definite quality of life improvement over a 1700X
- Ram finally runs at rated speed
- Works with X370 chipset after a couple bios updates, so didn’t need to spend on a new mobo

Cons: - takes a few bios updates for most motherboards

Overall Review: Since this has been installed, it’s been a pleasure to have in the machine over a 1700X. First boot took some time to adjust to the new CPU, but once everything was running, everything felt smoother. Less stutter, less slowdown. The computer is much more transparent, as it should be.
