Please research online with PC GPU reviews which card best supports 4K.
In regard Lumion running under 4K resolution, as previously, there will be a big impact on FPS. The final FPS you get will depend on the complexity and detail in the scene. The previous post at least gives you a guide as to change in FPS.
You can generally work OK in Lumion in Build Mode with FPS ranging as low as 10FPS, but 20FPS or above does allow for better response time when placing or moving things around. If things get slow, there are options in terms of editor settings to get some FPS back
Lumion does not support dual-chip cards such as the Titan Z or radeon r9 295x2. It works on the one GPU so for Lumion the other GPU is redundant.
The GTX 980 has the highest Passmarks, but with 4GB VRAM. The Titan Black does well in Passmarks but with 6GB VRAM. The amount of VRAM that might be used is dependent on the complexity of the scene (re hardware requirements link), so you need to consider current visualization projects or opportunities along with a little bit of crystal ball gazing. There are options that can be used in Lumion to manage texture demands for the GPU if needed, so more is always better, but not always required.
There is a price difference between the GTX 980 and the Titan Black.
Look forward to seeing you on board, let us know the PC you decide on and post a Benchmark once things are sorted
