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 brilliant single core score, this CPU is the business: 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 78.8%, this CPU's suitability for 3D gaming is good.
Boot Drive	75.1% is a good SSD score. This drive enables fast boots, responsive applications and ensures minimum system IO wait times.
Memory	24GB is enough RAM to run any version of Windows and it's far more than any current game requires. 24GB will also allow for large file and system caches, virtual machine hosting, software development, video editing and batch multimedia processing.
OS Version	Although Windows 10 is not the most recent version of Windows, it remains a great option.
