I'm a big fan of dual-core systems. I think there's a clear and substantial benefit for all computer users when there are two CPUs waiting to service requests, instead of just one. If nothing else, it lets you gracefully terminate an application that has gone haywire, consuming all available CPU time. It's like having a backup CPU in reserve, waiting to jump in and assist as necessary. But for most software, you hit a point of diminishing returns very rapidly after two cores. In Quad-Core Desktops and Diminishing Returns, I questioned how effectively today's software can really use even four CPU cores, much less the inevitable eight and sixteen CPU cores we'll see a few years from now.
