r/MachineLearning - [Project] hardware purchase for ml/cv project.

For my next job, I am tasked to build a rig for my ML project, centered on Computer Vision. Given that at my former places of employment, said material was always purchased by my employers before I joined the project, I have simply no idea of what it would be necessary to buy. However, I have yet no idea of the extent of the database, as there may be several phases of data acquisition. But I still need some good GPU to not lose too much time during the training process.
