First of all, the article linked to is fairly old in Linux terms and AMD regards.
Ubuntu works very well with AMD hardware, but your use should determine which Ubuntu version you need.
Ubuntu 16.04 LTS (Long Term Support) is primarily for you if you are going to use professional software such as CAD, OpenCL and similar software. AMD provides their own closes-source proprietary graphics driver on their website http://support.amd.com/en-us/kb-articles/Pages/AMDGPU-PRO-Driver-for-Linux-Release-Notes.aspx
However, if you don't know what any of this is, you might as well go with 17.04, since it has a newer kernel and therefore better hardware support - again, however, AMD's own closed source driver doesn't support this newer kernel, so you won't be able to install it on Ubuntu 17.04
Instead, you will be using the Open Source
radeonsi driver part of a project called MESA.
radeonsi is actually developed by AMD developers, and this is the driver you will be getting the best overall experience with.
The Open Source driver
radeonsi is the AMD driver with the best gaming support on Linux and also has no screen tearing. This is the recommended driver for most users.
The only downside of the
radeonsi driver, is that it is packaged alongside every major Ubuntu release (every six months). Therefore, you will not be getting the latest enhancements right away.
However, to that, there is a solution. If you want the latest drivers automatically, you can add something called a repository. There is a repository that will automatically update your open source
radeonsi driver everytime a new update arrives.
You can do that by opening a terminal
ctrl+alt+t (after installing Ubuntu), and enter:
sudo add-apt-repository ppa:paulo-miguel-dias/pkppa
press yes to add it and then:
sudo apt update && sudo apt upgrade -y
Lastly, reboot your computer and you will have the latest stable graphics driver installed.
There is only one caveat with adding this repository, which might be that you need to remove it before upgrading Ubuntu to let's say Ubuntu 17.10 when that arrives.
You can remove the repository by writing this in the terminal:
sudo apt install ppa-purge
sudo ppa-purge ppa:paulo-miguel-dias/pkppa
sudo apt update && sudo apt upgrade
When the new Ubuntu has been installed, simply add the repository again to automatically get the newest updates again. BTW, this repository also works on Ubuntu 16.04 LTS

You can download Ubuntu and try it out on your computer without installing it. You only need a USB Dongle and put a Ubuntu Live-Preview on it.
