Keep in mind that Opteron is a NUMA architecture. Local memory latencies are on the order of 95 micro-seconds, remotes on the order of 120. (Compare that to about 160 micro-seconds for the best intel SMP systems) While it performs well enough as a standard SMP once the OS's start to optimize for it's NUMA characteristics it will just get faster. If nothing else the Linux cluster market who desire 64-bit systems will keep Opteron alive commercially - the price performance is much better than any other 64-bit alternative, plus the Intel 32-bit compatiblity makes it a no-brainer.
