Fortnite FPS 1050Ti

Hello, I'm runninga 1050Ti with an overclocked 3770k and I struggle to get a stable >120 FPS.

It's about time I get a PC upgrade but I'm not sure whether to start with the processor or graphics card. I don't know whether my CPU is a bottleneck or not, so I'm curious to know if anyone else with a similar graphics card and newer processor gets a better framerate! I'm running all settings on low, except for render distance set to high.
