Guys, I think your fight overlooks simple fact of artificial obsoletion. Let's say that PCIe 6.0 x4 will provide sufficient bandwidth between CPU and GPU to handle memory transfers. But what about all those CPU+MB combinations that are going to be stuck at PCIe 3.0/4.0? Their CPUs will be perfectly fine for gaming on GPUs that do no have insufficient PCIe bandwidth. And I am sure, we do agree that even PCIe 4.0 x4 is not enough for GPU today. In future VRAM demands will go up. Display resolutions are getting higher in mainstream slowly, but they do. DX-R is said to require more VRAM too. So, what manufacturer would go and save pennies per card and lose all sales on older CPUs and MBs?
