Ah, I have more advice then. So most people build their PCs on PCPartPicker. Other than that you can find or make posts on Toms hardware, the LTT forums, the Reddit pc gaming sub, or even probably here. There are plenty of people much more skilled than I at picking parts. It’s somewhat of an art but you have to start somewhere. Also just consider your upgrade paths. Don’t buy a motherboard without knowing that there is a better CPU for the same socket. Stuff like that.
The college life is rough. I do it myself so I’d just keep in mind if you’re moving around a lot, you’ll need to be okay with moving the pc and it’s components. I move mine around often in a large case with a big monitor. It’s a task for sure. So consider building in a smaller case, it’s harder but may be worth it in the long run.
Not sure what kind of games you enjoy but steam loves their sales. Both the sales and humble bundle are a good way to try games for really cheap. Also steam let’s you refund games with less than 2hrs played. So trying things out for a bit and returning them is a very good deal. Also no subscription for online so that’s cool.

It’s interesting you bring that up. It annoys me slightly about the notifications but also I thought that my android phone spammed me with them. And they all got equal priority. So at least iPhone does do that better. I think for me it’s about equal there as well because I never took time on android to customize the notifications and I’d rather they all just act consistently.
