a 500 dually should be planty fast, although im not sure if those 2 500s act as a 1ghz in osx, or if the application has to be multithreaded
maybe somone could answer that
Acts as two 500MHz CPUs, the OS does a decent job of handling the threads in Tiger now.
But most apps aren't really multithreaded, unless you take a look at some of the Pro apps.
Even with BSDs SMPng, people still say there are some problems with the way Tiger handles threads and a ways to go.
But there is a lot to like about OS Xs SMP capability also.
OS X is much better than OS 9, which would basically make use of the machine as a single 500 MHz machine -- except for the apps that make use of the multi-CPU extension for some of their filters and plug-ins.
