PC StatusOverall this PC is performing above expectations (74th percentile). This means that out of 100 PCs with exactly the same components, 26 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith 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 64.5%, this CPU's suitability for 3D gaming is above average.
Boot DriveThe 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.
Memory4GB 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 VersionAlthough Windows 7 is still a viable option, it's now 14 years and 9 months old. This system should be upgraded to Windows 10 which is generally faster and has an improved set of core utilities including better versions of explorer and task manager.
Very high background CPU (35%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
