The other fact is that at work I use Opterons (three different systemsin my office, all of them dual CPU) and those systems are able to match or destroy (in some cases) the newer Macs (which we also have at work). The only time a Mac wins (against Intel ot AMD) is when you can fit your problem solution into Altivec and then spend some time optimizing it, which we have done in a few cases in the domain of signal analysis. Outside of the Altivec-unit the Macs are not going to win against AMD. Memory access latency is the killer for many apps, not the memory access throughput. In this sense most chess programs are limited by random access latencies and not be sheer throughput (as it is needed in video or signal processing). The dual-core G5s are not going to win the contest so easily against AMD in particular. (In fact I would pay extra to get OS-X run on an AMD processor) Anyway, enjoy your Mac for what it is, the best computer experience you can have today, and not for what it isn't the best chess playing computer in the world. If someone spent the time to translate (port) their chess algorithms to Altivec (if this is even possible) then your assumption _might_ have some merit. Until then, enjoy your computer and what you can do with it. :-) Regards, Hristo
