ProcessorWith an average single core score, this CPU can handle browsing the web, email, video playback and the majority of general computing tasks including moderate gaming when coupled with an appropriate GPU. Finally, with a gaming score of 39.2%, this CPUs suitability for 3D gaming is below average.
Graphics2.1% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
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 10 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 (25%). High background CPU reduces benchmark accuracy. Find active processes with Windows task manager (CTRL+SHIFT+ESC).
