should i get an amp or sound interface

so I'm getting my first guitar and want to know whether to get an amp or sound interface.

i will be playing mostly at home and i have a pc which i can connect a sound interface to.

what would be a good beginner amp or interface for a budget of around £200 and below?

would it be okay to use the same headset i use for gaming (hyperx cloud II) in a sound interface without sacrificing much quality?

edit: Thanks for all the responses, people are quite split between the amp and interface. I have read all the comments and spoke to someone at my local shop and will most be getting the orange crush 12 amplifier with an Ibanez gio GRX70QA
