Well, I wouldn’t say it like this, although its kind of true. I have worked with Rhino on €15k+ systems and on a €700 Laptop running Rhino. And my experience is, that for the majority of tasks (excluding Rendering), there is not a huge difference regarding performance. Why? Because it’s much more likely that both of these systems are either too fast or too slow. Of course, the workstation version of a €1200 gaming PC likely costs €2400, just because of having quality parts. But if the budget is tight, it’s totally fine to go for a gaming PC and call that a “workstation”… For rendering, there are great alternatives on a low budget system. You could make use of a render farm, or you can use ai-driven denoiser. GPU prices are out of control, but I’m pretty sure you can buy a used one, and even a RTX 2060 will perform good enough. At least I don’t see the need to pay €1000 for a medium graphics card at the moment.
But of course you are right. In the end, nobody in this forum is a true expert. My experience is rather that hardware performance is overestimated. Especially if you work on Grasshopper, the software part becomes the bottleneck, and so the user. Even in vanilla Rhino, the way you model determines the performance requirements of your system to a great extent.
