Let's compare prices and other things and find out. Also let's add in Ryzen and see how that affects price.
These aren't builds I'm recommending they are just there to help see what a broadwell-e vs skylake-x vs ryzen is like pricewise.

If I wanted to go with anything less than 10 cores Ryzen seems to be the best choice for price to performance. It seems like Skylake-X is usually a better deal than Broawell-E though. Skylake-X does have heat problems when overclocked but broadwell-e gets hot too when overclocked and can't clock as high. I think overall I'd go with either the cheaper platform Ryzen or the newer platform from Intel Skylake-x. Broadwell-e Doesn't seem to be worth it compared to either of those options.
