Yes, that will be required.
You can keep the K600 for other CAD work, and just add a more powerful (GTX or Radeon) GPU, and then assign it for use of Lumion.
I note the Thinkstation specs mention that it includes an IntelÂ® HD Graphics P4600, so that may be running Lumion by default and you would need to check (if not done so) that the K600 is assigned in the NVIDIA Control Panel to run Lumion. Even so, as previously mentioned, the K600 is well below minimum requirements for Lumion.
