Basically a well-binned i7 5930k for cheap. It's multiplier unlocked and overclocks like a champ! I got 4.1ghz on 1.15 volts! I'm positive I could go higher too, but the extra heat and/or time for fine tuning isn't worth it to me. It's cooled quite adequately by a CM 212 Evo Black edition, never reaching 70 C under load. Overclocked, it's better than a ryzen 1600, but even cheaper.
X99 Motherboards aren't easy to find cheaply, but if you can find one they're fantastic.
