OBS CPU or GPU?

I would like to start streaming Fortnite and wanted to ask if I would rather stream with my GPU or CPU at Fortnite always 100-150 fps

GPU (graphics card): GTX 1050ti

CPU (processor): AMD FX-8300

With the GPU.

The GPU

OK thanks. But would not Fortnite then lag?

I would say minimal because streaming is mainly on the internet.
