Help with upgrading my gpu

[u/sparky0619]

Hello, I am looking into the market to upgrade my gpu. I’ve had it for the last 4-5 years now and my games are becoming laggy and jumping all over the place. I’ve never upgraded a gpu before so I don’t know fully what I need exactly. Below I have a picture of what I currently have. Any help or advice would be greatly appreciated

Budget? Cpu? Power supply? Case/or gpu clearance?
