rocket league machine

i currently have a teenager who is obsessed with playing rocket leauge. the purpose of this build was to create something that would ease the conflict he's having with his siblings over access over a single nintendo switch console. the parts of this build were chosen with two things in mind. #1 budget, keeping costs down as much as possible and #2, performance in rocket league. i'm sure there might be a cpu limitation or bottleneck with more demanding games, but this is literally only going to be used for rocket league. if he moves on to a more demanding game in the future, then there's always the potential to upgrade the cpu and / or the graphics card.
