Of the last gen stuff, the 5800x3D is arguably among the best bang for buck, including for use in gaming builds. The applications where Intel's 12900K/12700K hold a significant advantage against the other chip with its 96MB of L3 cache typically aren't applications desperately in need of cpu power. IME it's poorly-optimized or hard-to-optimize software with bad cache coherency that most demands speed, and it's in those cases that the X3D delivers.
