I have a similar set up, so I know it works. Only difference is I'm running with an RX580.

Go into the Scene Configuration, select OpenCL Rendering. You should see a list of OpenCL devices and one should be your RX480 but it's listed as the GPU's chip name. In my case it says Ellesmere. Make sure you check the box. You can also check your CPU box.

I just got this software yesterday, so I'm no expert yet, but it seems like you can pick the threads and it automatically leaves one open. So if you have 8 threads available[image][/image], it'll use 7. That should keep your computer at least marginally responsive while rendering.
