So, the trap of modern game setups is that there is a lot of super high powered hardware out there- but unless you're driving 4K monitors at 120hz+, or striving for super fast 360hz+ refresh rates for competitive gaming, you don't need any of it. And people often get too caught up in the flashy new latest-and-greatest to recognize what's a good deal and what's just showing off.
Define your use case. What's your desirable budget? What kind of games do you want to play, do you want to do VR, what kind of display do you plan on using. Because while it's easy to drop $2800+ on hardware these days (like I did), it is still very possible to end up with a $900-1k machine that is super capable at 1440p and can run most all games you throw at it for at least another 5 years. Dpending on what exactly you want to do with it, prioritizing certain areas of hardware over others will pay off.
