So I recently bought my 480, hardware install is fine, windows and Radeon recognise the device and I've downloaded the latest drivers. Now the issue seems to be that it's still using my R7 integrated graphics are the primary and has my 480 disabled and I can't seem to find any way to enable it. Having gone into Radeon Setting>Additional Settings I have NO options to change GPU, the only options are for my VGA display and Audio. Can anyone lend me a hand please?
You need to get into the bios and disable your onboard graphics. There is a toggle that says "Use Intergrated Graphics Yes/No" or "UseDiscrete GPU"....I'm not sure what MOBO you have but that will do it.
If you are meaning an APU then follow this guide: Disabling a APU graphics - AMD - CPUs
