ProcessorWith 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 66%, this CPU's suitability for 3D gaming is above average.
Graphics5.89% is a very low 3D score (RTX 2060S = 100%). This GPU can only handle very basic 3D games but it's fine for general computing tasks.
Memory8GB 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 VersionAlthough Windows 10 is not the most recent version of Windows, it remains a great option.
