PC Status	Overall this PC is performing above expectations (68th percentile). This means that out of 100 PCs with exactly the same components, 32 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 very light workstation, and even some very light server workloads. Finally, with a gaming score of 77.3%, 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	105% is a very good SSD score. This drive is suitable for moderate workstation use, it will facilitate fast boots, responsive applications and ensure minimum 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 7 is still a viable option, it's now 14 years and 8 months old. This system should be upgraded to Windows 10 which is generally faster and has an improved set of core utilities including better versions of explorer and task manager.
