Im looking for changing my old rig for around 400$ and here is what i need. First i wanna know is is cheaper to buy prebuilt or custom if custom is answer here are my needs. I need something new that can run games like csgo 150+ fps like ryzen 5 3400g which is actually one of my goals. I need specifically components. And to be BEST and least trouble i can get for as cheap as i can get. Old gpu was giving me literally a problems constantly, crashing black screens restarts etc.
