Intel core i3 gen 6-7 or i5-7 gen 1-3?

Question

Processors

Hello, I'm still assembling a computer for 10 tr))) Thanks to everyone for the previous answers, I finally began to understand a lot. Actually now the question is, is it better to take a 1-3 generation intel core i5-i7 or a new 6-7 generation i3? There will be no video card, so the i5 and i7 of the 1st generation disappear ..
