The real question is whether CL, E-on, Corel, etc, will bother to port their apps over to X86-64. And from the available anectdotal evidence, it would be extremely worth the minimal investment in time (at least one of those database ports took one programmer a grand total of two days to port and recompile) for all of them to do so. The only thing I wish AMD had done is put the memory controller on its own slab, with either a Hypertransport interface to the CPU, or a seperate bus (whichever would prove to be faster), so that you could upgrade your mem capabilites without having to replace your processor....
