I currently have a Radeon R7 200 series and an FX-4300. My pc runs most games on low-med settings and only reaches near 60 fps on games like csgo. I only want to be able to run games like apex legends at 60 frames on high settings and some big titles at med-high settings. I also want to be able to render and edit videos more smoothly in sony vegas, so that's why I'm asking for GPU recommendations. I live in the US and my budget is around $250
