I wouldn't say that. If you plan on running more than 2 video cards or lots of M.2 or PCI storage then the 40 lane chips may be useful. Otherwise the only difference between the 6 core 6800k and 6850k is the number of PCI lanes and a couple hundred dollars. Consider if you really need the extra lanes before spending the extra money. The Haswell-E 5820k is also a fine option at a cheaper price. Broadwell-E is newer but only offers a slightly higher IPC while generally clocking lower meaning the chips perform almost exactly the same most of the time. Base clock is meaningless if overclocking is to be done and it would be silly not to on a build like this. The 6850k and 6900k clock pretty much exactly the same, somewhere in the 4.2-4.4 GHz range for most chips. Haswell-E tends to do a little better in the 4.4-4.6 GHz range but again with a slightly lower amount of work done per clock cycle so the performance roughly evens out.
If you're doing CAD work then that does justify X99 a little more. Have a look at benchmarks for the programs you use and see how many threads they actually utilize. Some programs really use everything you throw at them and would really benefit from more cores if you do want to spend the money on a 8 core chip.
