Question 1440p gaming/streaming/editing introduction

[yeetbucket]

I am fairly new to the pc gaming, but I know some stuff about it. This topic I need help on though. I want to get into 1440p triple a gaming, streaming, and video editing. If anyone has the time to tell me the parts I should pick. My monitor is going to be a 2560x1440p @144hz g-sync. Also, I would prefer a Nvidia GPU, because I want to take advantage of RTX and DLSS enhancements. Thnk you to anyone who responds
