The finance industry have some really whacky requirements. HFT firms often use heavily overclocked servers with HEDT processors, because microseconds of latency on a server request have direct monetary implications. I can't think of an application that would justify paying $5000 for an extra 300MHz of base clock, but I can imagine that someone needs it.
If your DC had limited rack space it might start to make sense. Buying a cheaper processor means you would need more of them to accomplish the same amount of work, but also you need more space.

Not just rack space. If workloads have to be on the same machine or socket (not NUMA/RDMA friendly), your only choice is to get bigger and bigger processors.
