PC StatusOverall this PC is performing as expected (50th percentile). This means that out of 100 PCs with exactly the same components, 50 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith a below average single core score, this CPU can handle email, web browsing and audio/video playback but it will struggle to handle modern 3D games or workstation tasks such as video editing. Finally, with a gaming score of 39.9%, this CPU's suitability for 3D gaming is poor.
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.
Memory3GB 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. 3GB 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 12 years 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.
High background CPU (24%). High background CPU reduces benchmark accuracy. How to reduce background CPU.
