ProcessorWith a brilliant single core score, this CPU is the business: It demolishes everyday tasks such as web browsing, office apps and audio/video playback. 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 79.9%, this CPU's suitability for 3D gaming is very good.
Graphics125% is an outstanding 3D score, it's the bee's knees. This GPU can handle almost all 3D games at very high resolutions and ultra detail levels.
Boot Drive272% is an exceptional SSD score. This drive is suitable for heavy workstation use, it will facilitate fast boots, responsive applications and allow for fast transfers of multi-gigabyte files.
Memory32GB is enough RAM to run any version of Windows and it's far more than any current game requires. 32GB will also allow for large file and system caches, virtual machine hosting, software development, video editing and batch multimedia processing.
OS VersionWindows 10 is the most recent version of Windows, and the best to date in our opinion.
High background CPU (21%). High background CPU reduces benchmark accuracy. Find active processes with Windows task manager (CTRL+SHIFT+ESC).
