What's the difference between the top two options? Apart from the fact that the 2nd one yields a .pkg that Installer says it can't open, that is...

I'm running the top one at the moment, with switches -smp -forceasm -advmethods - are there other switches I should be running (or any of these I should not be running, or running differently) for optimum performance?
I only see one FahCore_A3.exe process running in Activity Monitor (the last time I was running fah, on my mbp, it showed 4 separate processes) - is this just a change in how the app uses the system? AM seems to show both processors being used.
Thanks in advance for your time.
