Performance Results


Gaming 7% Tree trunk	Desktop 60% Destroyer	Workstation 7% Tree trunk


PC Status	Overall this PC is performing above expectations (70th percentile). This means that out of 100 PCs with exactly the same components, 30 performed better. The overall PC percentile is the average of each of its individual components.
Processor	With a good single core score, this CPU can easily handle the majority of general computing tasks. Despite its good single core score this processor isn't appropriate for workstation use due to its relatively weak multi-core performance. Finally, with a gaming score of 59%, this CPU's suitability for 3D gaming is average.
Graphics	3.15% is too low to play 3D games or use CAD packages. (Note: general computing tasks don't require 3D graphics)
Boot Drive	85% is a very good SSD score. This drive is suitable for moderate workstation use, it will facilitate fast boots, responsive applications and ensure minimum IO wait 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 10 is not the most recent version of Windows, it remains a great option.
