Will there ever be a high performance GPU integrated? Like everyone else I would never use integrated graphics because I play 3D games and have huge monitors. But if I could get 6 BD cores and an HD6970 all in one chip I would be all over it!

It seems like once the GPU and CPU are no longer separate components the drivers could leverage assumptions about the available CPU resource to squeeze out more performance. Instead of SLI across the PCIe bus and potentially bottlenecking the CPU we could get 4-8way workstation boards for SLI over hypertransport and increase CPU and GPU power together.

As far as the upgrade path it wouldn't bother me not being able to upgrade the CPU and GPU separately. Hell if I had spare sockets available it would be more flexible to be able to add the latest cpgpu alongside my existing chip for maximum performance anyways.
