Hi yaser bankhar
Small note that on the NVIDIA web site I see only the GTX 1080 as being their most recent high end card. Some other web sites discussing the GTX 1080 Ti are that the product is currently speculation, not released, and earliest quarter 4 of 2016. So the only information we can compare is against the current GTX 1080.
We have some users who have more recently started using the GTX 1080. Please go by the Passmarks score as that is the indicator we use.
There is no 'best' graphics card, it depends on what your budget is and what sort of Scenes will be rendered:
1. The GTX 1080 had been the highest performance card.
2. The new GTX Titan X (Pascal) is getting a better Passmark of 13380 compared to the GTX 1080 of 12646. It also has 12GB of memory compared to 8GB in the 10080, so that extra 4GB will help with Scenes that require more graphics resources.
3. The new Titan X (Pascal) also has 3584 cores and a larger memory bandwidth. But the clock is slower than the GTX 1080.
For Lumion the GTX Titan X (Pascal) would seem better suited to Lumion 'extreme' needs.
re CPU: of the i-7 range the Intel Core i7 â€“ 6950X 3.0 GHZ does seem to currently have the highest specifications if you look at the 3.5Ghz model. It has more cores and threads but a lower clock than the next one the Intel Core i7-6900K Processor. However cores and threads are not important after a certain point for Lumion. As Morten says, it's the clock speed, so that the CPU can keep up with the GPU.
The Xeon range E5-26xx series seems to have higher Passmark than the best i7. However, that is expected as they can have double the cores (not that important to Lumion), and of course are much more expensive.
If there is no budget limit, then the best you can go for in a Lumion based PC are those parts that have the highest specifications, performance and also quality. That also includes getting the fastest RAM.
It' never an easy decision. All the best with that process. Let us know how you get on. Looking forward to seeing some of your Lumion renderings at the Gallery.
