i disagree on this disagree. two heads are better than one, as long as the OS supports smp...one cpu could do something for an OS process while another runs an application or the like. anyway, one usually adds another cpu not for redundancy. geez, how many of you use smp because you want a backup cpu? we do smp because we want the added processing power...at the risk of another cpu failing. but hey, what's the statistic of a failed cpu on a multi-processor machine? i think it's easier for a hard disk to fail than a processor...well, maybe the processor fan. but that's what the cpu fan monitor is for.
on the example of P3-800 vs dual p2/c-400, of course you'd have reason to doubt the dualie. the p3 would most probably be sitting on a newer motherboard with a newer chipset with higher memory bus bandwidth than those p2s, which are probably using a two to almost three years old mobo. still, i'm not too sure...i bet the dual given a good smp os could still give the p3 a run for its money. -v Ian C.
