My opinion is that most processors and graphics cards, regardless of brand, are priced in a manner that reflects their price quite well. This is not linear though, it is more of a curve if you were to graph out price per performance. With the Athlon IIx4 representing excellent value and the 980X representing little performance increase for the cost.
Is this thread just personal interest or are you asking the question because it relates to a potential build of yours? Regardless, what would be the purpose of the system at this pricepoint? Gaming? Video rendering? server?
