I never liked the 1500x, because it's basically an expensive 4 core/8 thread Ryzen. In most cases you'd be better off with a 1400 and use the money elsewhere, considering the level of videocard you're likely to want to use in such a system. A jump to a 1600 is called for if the 1400 isn't enough for some reason. And now with a 2600 as an option the 1500x looks even less attractive.
