It depends. You should probably use the amd64 version of you want to use more than 4GB of memory. EMT64 is just intel's term for a chip that uses AMD's 64-bit extensions to x86 architecture. Before installing the amd64 version however, make sure that none of the ports you want to install has "ONLY_FOR_ARCHS=3Di386" set in it's Makefile. (And note that "ONLY_FOR_ARCHS=3Di386 amd64" is fine). If you have more servers running i386, and want to centrally compile kernels and ports, it might be better to stick with i386. It is not possible to make a general prediction as to which architicture is faster; that will depend on the workload.
