PC Status	Overall this PC is performing above expectations (65th percentile). This means that out of 100 PCs with exactly the same components, 35 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With an outstanding single core score, this CPU is the cat's whiskers: 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 91%, this CPU's suitability for 3D gaming is excellent.
Graphics	51.2% is a reasonable 3D score (RTX 2060S = 100%). This GPU can handle the majority of recent games but it will struggle with resolutions greater than 1080p at ultra detail levels. (Note: general computing tasks don't require 3D graphics)
Boot Drive	63.6% is a good SSD score. This drive enables fast boots, responsive applications and ensures minimum system IO wait 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.

Sub-optimal background CPU (18%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
