It will take forever for Intel and AMD to get their acts together :( AMD did well by putting the memory controller on the CPU, but Intel didn't. Intel added "IOA/T" (async DMA memory copies), but AMD doesn't have that. And ATI/NVIDIA stuff will likely remain across the PCI-Express bus for quite a while. My preference is to have ATI/NVIDIA use the same PCI-Express interface, and differentiate in the GPU.
