For $800 you can expect to put together a system that can max out any game on 2560×1440 resolution. And, you can even expect a $800 gaming computer to serve as an entry-level 4K gaming computer.                                                                                                                                 

The $800 mark is the sweet spot for building your own computer, as $800 in components is enough to provide optimal in-game performance while still maintaining a reasonable budget.
