PC Status	Overall this PC is performing as expected (54th percentile). This means that out of 100 PCs with exactly the same components, 46 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With a good single core score, this CPU can easily handle the majority of general computing tasks. 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 57.6%, this CPU's suitability for 3D gaming is average.
Graphics	6.24% 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.
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	Windows 11 is the most recent version of Windows.

Very high background CPU (31%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
