Okay, I understand. You're looking for a computer with multiple NVIDIA GPUs and high VRAM, specifically for AI video diffusion tasks. This kind of work benefits greatly from parallel processing capabilities.

Okay, I've reviewed the search results. It seems like we're getting a mix of individual high-end NVIDIA GPUs, workstation motherboards that support multiple GPUs, and complete workstation PCs.

To narrow down the search and provide you with the most relevant options, let's clarify a few things:

1. Are you looking for pre-built workstations or individual components to build your own?
2. How many GPUs are you planning to use for your AI video diffusion work? This will help determine if the motherboards listed are suitable.
3. What is your budget? Knowing your budget will help me filter the results and focus on options that are within your price range.

In the meantime, let's look at some of the more promising results:

• PNY NVIDIA RTX 6000 Ada Generation 48GB:
• PNY NVIDIA RTX A6000 Professionelle Grafikkarte 48GB:

These cards both offer a substantial amount of VRAM, which is essential for AI video diffusion. The other results are either motherboards (which require you to source other components) or complete workstations with a single, less powerful GPU (like the RTX 4070 Ti Super).

Let me know your answers to the questions above, and I can refine the search further!
