Building your own gaming PC is incredibly rewarding - here's what you'll need
For me, I simply prefer the trusty keyboard and mouse, and I can't get used to controllers for first-person-shooter games. Plus, games can look better on PC than they do on consoles, and you can use it as a computer for work, or whatever else.
For those looking for ideas on what parts to get, I've compiled a list for a powerful gaming PC that'll handle pretty much any game now and for the next few years at high graphics settings and frame rates.
You can certainly look at less powerful parts, but I included higher-end components for future-proofing reasons, hence the leaning towards quality over value for this build.
