The bigger question, at least for me, is either high-core machines improve your desktop experience if you're mostly running low-threaded workloads, for example a web browser. One humble piece of evidence I gathered says that no, more cores make your low-threaded applications run slower because the Linux scheduler keeps placing them onto "cold" cores running on idle frequency, and once they "spin up" the thread gets moved to another cold core.
