If you work with numbers above 2 billion, then 64 bits is useful to some extend. In chess i work with things like pawn = 1000 points, knight = 3500 points. So i do not get close to 2 billion soon. So for DIEP there is not much advantage in 64 bits. 32 bits is plenty for me. Note that for business applications which work with numbers, there is a special part of the processor which is 80 bits. It is the FPU, or floating point unit. It is doing math only. Nowadays this part gets sold as 'mmx', after they extended it a bit. AMD might extend it even a bit further than just mmx to a full 64 bits co-processor. So for companies there is not much interesting in getting a 64 bits processor either. The ones who need a 64 bits processor are guys like Bob who rewrote their chessprogram to something making use of big numbers, exactly 64 bits numbers. Perhaps i can find a reason why i need to drive a mercedes instead of an opel corsa :) Anyway, crafty has advantage with 64 bits processors. I do not. Best regards, Vincent
