More fun in benchmark land
This is going to be subverted six ways to Sunday. It will be impossible to get reliable data because every vendor is going to criticize the other vendors' results with endless discussions on how a given parameter skews the results and should have been set to something else, with the other vendor replying in length about how that change would only skew in some way favourable to the first vendor, etc. etc.
Of course, maybe I'm wrong and the benchmark results will be taken as canon by everyone, but given the historical battles we have already witnessed in the business arena as well as in the graphics arena, I doubt it.
