fahinfo.org is a database of collected Folding@Home project scores. The scores are submitted along with details about the CPU on which they were run. This information will show which workunits are best (and worst) for specific CPUs, and also highlight the differences between the different cores on the same CPU type. The more data collected and added the better, as this will serve to make the PPD/GHz values more accurate. You can lookup the work-unit (by project number) you are currently running to see how well it could or should be doing on your particular CPU, I might even make it recommend the CPU that you should be using for that WU. This site was written by and is maintained by me, Uncle_Fungus, and has been hand-coded from scratch in PHP and MySQL.

The WU Search page has been updated to now include data specifying the minimum CPU speed required for each architecture in order to meet the deadline. This is calculated based on the preferred deadline and not the final deadline, since results returned after the preferred deadlines are scientifically useless.
SMP WUs will show an information bar informing you that you need to divide the recommended CPU speed by the number of CPU cores that the SMP client is using. This is necessary since the data is stored per core and not per client.
I am aware that PPD doesn't scale linearly with core count, but this is more to provide a reasonable estimate rather than an authoritative value.
