| PC Status | Overall this PC is performing as expected (48th percentile). This means that out of 100 PCs with exactly the same components, 52 performed better. The overall PC percentile is the average of each of its individual components. |
| Processor | With 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%, this CPU's suitability for 3D gaming is poor. |
| Graphics | 0.72% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics) |
| Boot Drive | The 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. |
| Memory | 8GB 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 Version | Although 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. |
