PC StatusOverall this PC is performing below expectations (38th percentile). This means that out of 100 PCs with exactly the same components, 62 performed better. The overall PC percentile is the average of each of its individual components. Use the charts in the benchmark sections of this report to identify problem areas.
ProcessorWith a relatively low single core score, this CPU can handle email, light web browsing and basic audio/video playback, but it will struggle to handle CPU intensive tasks. Finally, with a gaming score of 32.2%, this CPU's suitability for 3D gaming is poor.
Boot DriveThe boot partition is located on a mechanical or hybrid drive. Moving the system to an SSD will yield far faster boot times, better system responsiveness and faster application load times.
Memory3GB is enough RAM to run any version of Windows and although it's sufficient for most games, some will benefit from up to 8GB of RAM. 3GB is also enough for modest file and system caches which allow for a responsive system.
OS VersionAlthough Windows 10 is not the most recent version of Windows, it remains a great option.
Very high background CPU (96%). High background CPU reduces benchmark accuracy. How to reduce background CPU.

EDIT WITH CUSTOM PC BUILDER
Why does UserBenchmark have a bad reputation on reddit?
Marketers operate thousands of reddit accounts. Our benchmarks expose their spiel so they attack our reputation.
Why don’t PC brands endorse UserBenchmark?
Brands make boatloads on flagships like the 4090 and 14900KS. We help users get similar real-world performance for less money.
Why don’t youtubers promote UserBenchmark?
We don't pay youtubers, so they don't praise us. Moreover, our data obstructs youtubers who promote overpriced or inferior products.
Why does UserBenchmark have negative trustpilot reviews?
The 200+ trustpilot reviews are mostly written by virgin marketing accounts. Real users don't give a monkey's about big brands.
Why is UserBenchmark the gold standard for users?
Instead of pursuing brands for sponsorship, we've spent 13 years publishing real-world data for users.
