PC Status	Overall this PC is performing as expected (51st percentile). This means that out of 100 PCs with exactly the same components, 49 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. Despite its good single core score this processor isn't appropriate for workstation use due to its relatively weak multi-core performance. Finally, with a gaming score of 71.9%, this CPU's suitability for 3D gaming is good.
Graphics	37.8% 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	68.9% is a good SSD score. This drive enables fast boots, responsive applications and ensures minimum system IO wait times.
Memory	8GB is enough RAM to run any version of Windows and it's sufficient for the vast majority of games. 8GB is also enough for moderate file and system caches which result in a very responsive system.
OS Version	Although Windows 10 is not the most recent version of Windows, it remains a great option.

Sub-optimal background CPU (15%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
