Isn't the advantage of Opteron the superior IO architecture? There is not much advantage with 64 bit computing. What is faster about it? Pointers are bigger, so it use more cache for less. NOt much 64bit math in OS. Why do you say it will perform worse? Boris __________________________________ Do you Yahoo!? Yahoo!
