Because of the way attribute points and bonus points scale, i.e. the higher an attribute goes the more bonus points you need for each additional point in the attribute, you don't have a fixed number of attribute points. What I can tell you is that 80-80-92-92-80-80 is a valid assignment. So if you get all to 80 first you effectively have 24 points. If you look up the scaling in particular and do the math you can determine your total number of bonus points.
