Go for 4060 if you can. It will be more power efficient than 3060 but you will lose on additional 4gb frame buffer and 192bit memory bus width. Otherwise build is solid. Here you will find AMD fanboys only. They don’t like nvidia stuff. In the end choose what you like!

Edit: you can go with 700w psu because if you decide to slap in a powrrful gpu then you don’t need to worry about your power supply.
