PC Status	Overall this PC is performing as expected (40th percentile). This means that out of 100 PCs with exactly the same components, 60 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With a relatively low single core score, this CPU can handle email, light web browsing and basic audio/video playback, but it will struggle to handle CPU intensive tasks. Finally, with a gaming score of 34.3%, this CPU's suitability for 3D gaming is poor.
Graphics	5.54% is a very low 3D score (RTX 2060S = 100%). This GPU can only handle very basic 3D games but it's fine for general computing tasks.
Boot Drive	38.8% is low SSD score. With a better SSD this system will boot faster, make applications more responsive and reduce IO wait times.
Memory	4GB is enough RAM to run any version of Windows and although it's sufficient for most games, some will benefit from up to 8GB of RAM. 4GB is also enough for modest file and system caches which allow for a responsive system.
OS Version	Although Windows 10 is not the most recent version of Windows, it remains a great option.

Very high background CPU (56%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
