PC Status	Overall this PC is performing above expectations (65th percentile). This means that out of 100 PCs with exactly the same components, 35 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With a relatively low single core score, this CPU can handle email, light web browsing and basic audio/video playback, but it will struggle to handle CPU intensive tasks. Finally, with a gaming score of 27.8%, this CPU's suitability for 3D gaming is very poor.
Graphics	4.81% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
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	4GB is enough RAM to run any version of Windows and although it's sufficient for most games, some will benefit from up to 8GB of RAM. 4GB is also enough for modest file and system caches which allow for a responsive system.
OS Version	Although Windows 8.1 is a recent version of Windows, it's worth upgrading to Windows 10 which has had several improvements made to the user interface including a better homescreen.

Very high background CPU (35%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
