PC Status	Overall this PC is performing below expectations (32nd percentile). This means that out of 100 PCs with exactly the same components, 68 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
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 44.2%, this CPU's suitability for 3D gaming is below average.
Memory	16GB is enough RAM to run any version of Windows and it's more than sufficient for nearly all games. 16GB also allows for very large file and system caches, software development and batch photo editing/processing.
OS Version	Although Windows 10 is not the most recent version of Windows, it remains a great option.
