The question noone seems to have asked here is, what OS? If it is Windows either should be ok. Even tho the AMD 64 has better memory management and is better for server's. If it is Linux I would only go with a AMD64. That way you can run full 64bit linux. You will notice a difference there. Especially if it is hosting.
And for those that compare Mhz stick with cropping your TGP images.
