If you can afford one, I highly recommend an SSD (Solid State Drive) as your primary drive (generally at 250 or 500 Gigabytes).When possible I recommend 6 GB or more, especially if you are rendering or handling large models or data sets.

4 GB dedicated Workstation class Video Card as a bare minimum (NVidia Quadro or AMD FirePro), You can probably make out fine with 2GB for most LT applications, but more is better, and it must be Workstation class – gaming cards will not cut it for performance.

You will want 32 GB or more if you are working with large models or animations

16 GB of RAM minimum, 8 GB might be okay for LT applications and Viewers, but as a minimum 16 GB.

(I generally steer away form Xeon processors, those have Server architecture and are generally not faster than a consumer processor)

Fastest Intel i7, Intel i9, or AMD processor you can afford (Minimum 3.0 GHz or higher) – Quad core or more if you have the budget (more cores is not necessarily faster, as most Autodesk Software is primarily single core/single thread) The faster the processor, the better the performance will be.

Here's a list of what I have put together for specs based on my own experience and usage: You've looked at the Autodesk website, and have looked at their minimum specifications, but don't see a recommended or ideal one. You are ready to buy a new computer for your CAD workstations, and are confused or unsure what the best setups are for what you do.
