im interested to know how folding works on the cards, are all vertex, geometry and pixel shaders all used? or does it use unified shader instructions that are sent across all three types of shaders. the 4870 has like 800 shaders, even if it wasnt under stress shouldnt it be able to process more in folding by using unified shader instructions? or does this come back to idea of having different types of shaders between ati and nV
