Assuming you have enough memory, conventional wisdom is to use 5 then.
I have 4 pretending to be 8, so that's what the 9 is about.  The next
generation Thinkpad would have allowed getting a processor doing that
without exceeding thermal design power.  But then I don't have a
discrete GPU and don't do a lot of video processing.  I still have the
original 2-core somewhere in a drawer.
