PC Status	Overall this PC is performing as expected (43rd percentile). This means that out of 100 PCs with exactly the same components, 57 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With an average single core score, this CPU can handle browsing the web, email, video playback and the majority of general computing tasks including light gaming when coupled with an appropriate GPU. Finally, with a gaming score of 53.9%, this CPU's suitability for 3D gaming is average.
Graphics	33.6% 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.

Very high background CPU (48%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
