Thank you very much for your answer. When I read my question, I saw that I could not express myself much. Even so, you answered my question mostly. Thank you...

Hi Cem, not sure exactly what you're asking here. But I'll give it a go, seems like you're asking whether building a single multi-GPU machine is better than two machines and using distributed rendering?

Depends on what you're doing. If you're wanting a workstation that can give you very fast previews that will let you develop your work quickly, then a multi-GPU system would be better in my opinion.

If you want a render farm to render projects, then having two machines can be a bit more flexible, you can render on one, work on the other, and then include the first node when you leave the office (crowdrender lets you add nodes to an animation render after you've started the render ). You can of course do this with just one computer and only allow the render to use some of the GPUs in your system. However working on that one computer while its rendering might be tricky since a large scene might consume sufficient RAM to make your system slow even if you're only rendering on the GPUs.

So depending on what you're doing there are different answers I'm afraid. My dad taught me a sound principle from his experience as a mechanic, always get the right tool for the job.

Hope this helps
