If your PC doesn't meet the Windows 11 requirements, or isn't compatible with the newer versions of SOLIDWORKS we would recommend upgrading.
Our recommended replacement cycle is 3-5 years for SOLIDWORKS users, as that provides the best trade-off between expenditure and performance gains.
To give you an idea of the significance of upgrading PCs for CAD work, we compared a high-end Precision 3630 system from 2018 with our latest recommended Precision 3680 Desktop. For typical CAD tasks like part modelling and navigating large assemblies, the 3680 workstations performed around twice as fast.
The newer versions of SOLIDWORKS also offer many performance improvements, so upgrading you hardware and software together can be hugely beneficial.
