As with most things, it is all dependent on what your reference point is. If for instance you are talking RC5-72, then yes, ATI's reign supreme, however you can say the same if you are talking folding@home as nvidia is the gpu card in that world. It's just like the old intel vs amd thing, when in reality it depends what you are working on as they each have their strengths and weaknesses. So really, one needs to qualify what one gpu is better at since neither one is better at everything just like with cpu's. :-)
