A bit off base

While your article has merit, a few things you have over looked. There is a water Simulation out using a 980X i7 CPU where all 12 core(6 real and 6 virtual) are pegged at 100% and it still GETS trounced by a 9600GT running the same simulation. A peformance differnce of around 10x if I recall correctly. And the code run on the i7 was changed to run SSE code paths. So the boost could be seen, but the GPU is and will always be magnitudes faster than CPU regardless of the code paths.
