PC Status	Overall this PC is performing above expectations (76th percentile). This means that out of 100 PCs with exactly the same components, 24 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With an outstanding single core score, this CPU is the cat's whiskers: It demolishes everyday tasks such as web browsing, office apps and audio/video playback. Additionally this processor can handle light workstation, and even some light server workloads. Finally, with a gaming score of 88.1%, this CPU's suitability for 3D gaming is very good.
Boot Drive	63.6% is a good SSD score. This drive enables fast boots, responsive applications and ensures minimum system IO wait times.
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 7 is still a viable option, it's now 14 years and 8 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.
