PC StatusOverall 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.
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 65.1%, 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 VersionWindows 10 is the most recent version of Windows, and the best to date in our opinion.
