Does anyone know if AMD has good drivers for linux for their apus?

I building a dedicated Linux machine and I plan on using AMD for the price. I plan on running 2 or 3 monitors so I thought that the apu line from AMD would be fine and if I need more monitors I could just add a GPU later. I was wondering if the drivers for AMD work well with Linux.

so far they work better than nvidia; either way nvidia doesn't have good support for many monitors.
