I remembered when I made my Socket 939 with Nforce 4... It was so sweet and give me confidence NV + AMD = Performance
Since AMD+ATI things are changed and NV left alone without solid direction, they made many things such CHIPSET, GPU, RE Labeled GPU, Optimus, Physx, Fermi, 3D Vision... but nothing comes as a killer product. In fact they miss the GPU schedule and try to gain popularity by creating 2D comic against Intel.
Fighting Intel in the chipset business is not a solution because every chipset must develop according to the processor and this always lead AMD+ATI or INTEL+INTEL ahead....
