Upgrade questions

I know this is a bit of a stupid question but I currently have a ryzen 5 8600g and a 16gb 4060ti o find for the games I play such as Microsoft flight simulator they are not that good for flying and great graphics. I don’t want to spend much but my price is in AUD I’m thinking a ryzen 7 7700x and a 4070, amd or a possible 50 series card.
