RTX 4060 upgrade disaster—games stuttering nonstop. Any solutions?

I recently just upgraded to RTX 4060 coming from a GTX 1660 super gpu. I was playing Hogwarts Legacy, Spiderman Miles Morales, and GoW. Then out of the hype, I don't even feel that my games are faster and I didn't felt that I upgraded.

Here's my current pc specs:
- Ryzen 5 5600g
- FSP SFX Pro 450w 80+ Bronze
- T.Create 2x8GB DDR4 3200mhz
- Gigabyte A520i AC Wifi

Am I in a deep upgrade rabbit hole now? Do I need to upgrade other components as well? Need help
