PC StatusOverall this PC is performing as expected (45th percentile). This means that out of 100 PCs with exactly the same components, 55 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith an average single core score, this CPU can handle browsing the web, email, video playback and the majority of general computing tasks including light gaming when coupled with an appropriate GPU. Finally, with a gaming score of 44.4%, this CPU's suitability for 3D gaming is below 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.
Memory8GB is enough RAM to run any version of Windows and it's sufficient for the vast majority of games. 8GB is also enough for moderate file and system caches which result in a very responsive system.
OS VersionAlthough Windows 7 is still a viable option, it's now 14 years and 10 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.
