Games, programs or workloads that it will be used for: battlefield 5, star citizen, bannerlord, city skylines, hogwarts legacy when it comes out and whatever game looks good mostly triple A

Other details (existing parts lists, whether any peripherals are needed, what you're upgrading from, when you're going to buy, what resolution and refresh rate you want to play at, etc):  https://au.pcpartpicker.com/list/RgZsW4 no peripherals needed. Already ordered gpu, cpu aoi and storage, monitor is shown in parts list and is the best one I can find that's curved and ultrawide. With 165hz and 1440p

 

Just need some advice and any other useful information. I'm also terrified about building it but I'm going to anyway.
