I don't think you need a better PC

This will hold true as long as OP doesn't trash his IDE's performance with too many plugins where even smaller project might run into performance issues if this mistake is made. But it doesn't mean OP has to distract themselves with learning a modal TUI editor, although it'll probably be beneficial for their productivity if they persevere and better to do that early than waste time hopping IDEs just for the sake of it. Tip for staying somewhat flexible if you still haven't decided yet is using something like vim plugin to vscode or vice versa, trying Neovim "distributions" (see awesome Neovim for some examples) and switching to a more feature-rich, GUI-based IDE.
