PC StatusOverall this PC is performing as expected (59th percentile). This means that out of 100 PCs with exactly the same components, 41 performed better. The overall PC percentile is the average of each of its individual components.
ProcessorWith a good single core score, this CPU can easily handle the majority of general computing tasks. Additionally this processor can handle moderate workstation, and even light server workloads. Finally, with a gaming score of 74.1%, this CPUs suitability for 3D gaming is very good.
Graphics16.2% is a below average 3D score (GTX 1070 = 100%). This GPU can handle older games but it will struggle to render recent games at resolutions greater than 1080p. (Note: general computing tasks don't require 3D graphics)
Memory64GB is enough RAM to run any version of Windows and it's far more than any current game requires. 64GB will also allow for large file and system caches, virtual machine hosting, software development, video editing and batch multimedia processing.
OS VersionAlthough Windows 7 is still a viable option, it's now 9 years and 2 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.
