It really depends on what you are doing, there are some functions that the retail consumer cards just don’t do. For a single user on a single workstation with a single card not going to be a huge difference unless you start getting into the AI stuff or any computational works that require real time error correction.Curious, do you see a big difference in using professional vs consumer gpu's and solidworks? I run a 3080 and even with complex assemblies, I rarely notice any slowdowns/issues.
But a multi user machine, one with multiple cards, or something running software sets inside a sandbox that requires the GPU to be virtualized then the difference becomes very apparent very fast.
