Makes no sense to compare a standalone cpu with a cpu with graphics chip, at this level of cpu, operating without a dedicated graphics card is pretty much out of question, thus the 990x not having a onboard graphics chip in not really a disadvantage, and should certainly not be a 20/60 point criteria!
