First gaming pc

Solution
It's awesome you have the desire to build your own PC.

You can build a system with a decent iGPU/APU and add a GPU later if you need.

With the budget AMD Ryzen 3 2200G it requires a bios update on AMD's budget motherboards. A real pain that AMD has presented (they ought to be ashamed). But you can request a boot kit from AMD to install a compatible CPU and administer the bios update yourself.
