field test their latest crap.
Nail on the head imho.
Personally I don't see a future in this technology. I think it would be better to create a dual-core GPU. I know it would be huge and run incredibly hot at first (Pentium D of the GPU world anyone?) but I think it has long since been realized that a single multi-core CPU is far more efficient and practical than multiple single-core CPUs. I believe the same logic applies to the GPU.
I'm not saying throw SLI out in general, but instead of tri-SLI you could end up with two dual-core GPUs in your box, which would result in more performance than this technology.
I would most expect a move to multi-core GPUs from AMD first, rather than nVidia.
