https://pcpartpicker.com/list/4z9dXPIf all you play is esports games, you could forgo the SSD, but if you play anything that loads while in game (open world, rpg, etc), I would strongly recommend an SSD as it will be a very noticeable improvement.
I will say however, unless you really have an Intel preference, or you plan on gaming at 120+ frames/second, you could go for an AMD Ryzen 1600 build and probably save almost $100 and it will handle streaming applications better (double the usable core count)
