The biggest fear I have if I upgrade to 13.04 is that the video driver I use will no longer work on the new version.
I'm currently using a AMD Radeon and the driver is here http://support.amd.com/us/gpudownload/linux/Pages/radeon_linux.aspx?type=2.4.1&product=188.8.131.52.42&lang=English
But I don't want to upgrade and find that the driver doesn't work. If I don't have a 3D driver the computer will be useless.
Can anyone confirm that these drivers will work with 13.04
