ProDigitMost boards are standardized. Only Dell and HP have their own motherboard and CPU connectors. I realize quadcores are very cheap, and probably can crunch the same amount of data (if they're running at 4+GHz) than the Xeon CPU I have running at 2Ghz. Still, there's something about running 40 threads of cpu tasks at a time, and potentially additional GPUs. For 8 threads (4 cores or more), CPUs are still quite expensive.
rchiwawaI'll believe CPU crunching is important when the points reward reflects it to be some sort of priority for Pande Labs
