PC Status	Overall this PC is performing above expectations (78th percentile). This means that out of 100 PCs with exactly the same components, 22 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 light workstation, and even some light server workloads. Finally, with a gaming score of 77.6%, this CPU's suitability for 3D gaming is good.
Graphics	7.84% 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	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	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.
