I would not buy an i3. I would much rather get a haswell i5 before a skylake i3.
The i3-6100 will beat an i5-2500k but only when paired with high speed ddr4 on a z-series MB which you pay extra for but in some games 4 proper cores will still beat the 2cores+2threads i3-6100. Recall this from a eurogamer/digital foundry benchmark. The newer i5's will do better.
