PC Status	Overall this PC is performing above expectations (79th percentile). This means that out of 100 PCs with exactly the same components, 21 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With a brilliant single core score, this CPU is the business: It demolishes everyday tasks such as web browsing, office apps and audio/video playback. Additionally this processor can handle light workstation, and even some light server workloads. Finally, with a gaming score of 78.8%, this CPU's suitability for 3D gaming is good.
Graphics	15.5% is a below average 3D score (RTX 2060S = 100%). This GPU can handle older games but it will struggle to render recent games at resolutions greater than 1080p. (Note: general computing tasks don't require 3D graphics)
Boot Drive	The boot partition is located on a mechanical or hybrid drive. Moving the system to an SSD will yield far faster boot times, better system responsiveness and faster application load times.
Memory	16GB is enough RAM to run any version of Windows and it's more than sufficient for nearly all games. 16GB also allows for very large file and system caches, software development and batch photo editing/processing.
OS Version	Although Windows 10 is not the most recent version of Windows, it remains a great option.

High background CPU (21%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
