Alrighty then...Mint installed and running CPU tasks, but there is no option to use the GPU, although Mint tells me the recommended driver is installed already for the AMD R9-280X. :\
It's been a long time since I used an AMD card but I would uninstall the proprietary driver that's distributed with linux mint and download and install the latest driver from AMD.
Here's a link from AMD on uninstalling and installing drivers.
Note on step 8: I believe you need run as "superuser" and the --force switch
sudo /usr/bin/aticonfig --initial --force
For versions of X.Org newer than 7, /usr/bin/aticonfig --initial to configure the driver for your AMD product.
For versions of X.Org older than 7, /usr/X11R6/bin/aticonfig --initial to configure the driver for your AMD product.
