Nvidia 750 ti

Hi, I just bought a 5700XT Red Devil to replace my 750Ti graphics card. I want to start streaming, and a thought came into my head and I didn't know if it was possible. I want to have the 750Ti to be my encoder for OBS and have it strictly do that, is it possible to do that with an AMD card in...

Motherboard, RAM, CPU. I have a case, 750w power supply. I've never looked for these individual parts before and don't know where to start. I play mostly RPGS and the sims 3. So my budget is around $500-700.
