$40 more for 100 more MHz on a 3700X, and $240 more for an extra 100 MHz on a 3800X???? <sigh!>
Good business model.....selling almost nothing for something...
To be fair, AMD is doing the same thing. A 3800X is nothing more than a 3700X binned for slightly higher clock rates and priced $70 higher. And the same goes for 3600X compared to the 3600, though with that processor you also get a somewhat better stock cooler for your $50.
It's also worth pointing out that the 3700X is a $330 processor, so $340 (plus shipping) for a binned one isn't exactly bad. The highest-binned 3800X for $610 is kind of silly though, since you could get a 9900K with slightly better lightly-threaded performance, or a 3900X with 50% more cores for significantly better multithreaded performance for less.
And they even admit that these processors are not really a good fit for aftermarket binning, since AMD seems to have them binned to begin with, and the processors take advantage of nearly all available performance even without manual overclocking.
