Can you jellies help me build a gaming computer?

A couple years ago I would have had no problem with this task but I’m afraid I’ve been out of this realm for quite some time now. I still know whats up with simple stuff like RAM and HD’s but when it comes to motherboards and video cards I’m honestly lost.
I’m tired of playing all my games on the lowest possible settings :(

Your mission, if you choose to accept, is to build me a computer that would be great for gaming and cost around $1,000

Thanks :)
