I'm not an Intel mouthpiece, and I still don't have a clue what regular power users (including me) use more than 4 cores for.
Speaking from experience, I don't run that many parallel workloads (I don't know how parallel my compiles are), but when I do, given a specific TDP for a desktop processor, and the asymptotically diminishing returns due to lower clocks speeds, more memory/cache contention and more synchronization, the benefits of going for more than 4-6 cores are negligible, for parallel workloads.
