PC Status	Overall this PC is performing below expectations (36th percentile). This means that out of 100 PCs with exactly the same components, 64 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
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 59.9%, this CPU's suitability for 3D gaming is average.
Graphics	3.87% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive	74.1% 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.

Very high background CPU (60%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
