Along with the other answers here, things like distributed processing projects tend to be embarrassingly parallel. I was running distributed.net OGR for a while, and that runs quite a bit better on many modest cores. Almost all my other programs bottleneck on disk / RAM speed, or RAM size... The OGR project in particular is also far more efficient on CPUs than on GPUs, since it is an entirely integer workload.
