PC Status	Overall this PC is performing as expected (45th percentile). This means that out of 100 PCs with exactly the same components, 55 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 62.7%, this CPU's suitability for 3D gaming is above average.
Boot Drive	198% is an exceptional SSD score. This drive is suitable for heavy workstation use, it will facilitate fast boots, responsive applications and allow for fast transfers of multi-gigabyte files.
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.

Very high background CPU (68%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
