I would absolutely have bought a 16 core TR3 for $900-$950 because I don't need 24 cores but I do need the PCIE lanes for 1 gpu (16 lanes), 5 m.2 SSD's (20 lanes), 1 dual 40GB NIC (8 lanes). Instead I'm stuck getting 24 cores and paying more, ah well.
What's the use case? I can't think of much that would leverage all that and not also love lots of cores.
