It's not really the cost that's noteworthy so much as a general lack of gaming-optimized CPUs with that many physical cores, and also that it just doesn't make sense in terms of playable resolution. With that core count you're looking at future hardware (for best general gaming performance) or workstation processors (for lower general gaming performance, but maybe best for sims). It's just kind of an odd recommendation, not saying that it is right or wrong.
