The link above is to the tested graphics cards. Ansys is guaranteed to work on one of those.
Most NVIDIA cards will work with Ansys, but they have not been tested and so are not guaranteed.
The same GPU chips are in professional level graphics cards as the lower cost gaming cards. The difference is the quality of the driver in providing an Open GL API that works with Ansys. The professional cards such as Quadro have invested in delivering high compatibility with Ansys and other CAD programs, while the gaming cards invest in delivering high compatibility with games.
I have run Ansys on an integrated graphics card, but the dynamic rotation was done in software and not on a hardware chip so was slow and jerky for large models. I don't know about the specific chips you are asking about.
You could purchase a used graphics adapter on ebay.com because people upgrade those faster than the computer so there are plenty of used cards for sale and the cost will be less than half of a new one.
