I'm tired of dealing with the disaster that is catalyst on a 4xxx IGP and I want to buy some discrete graphics that support both Unity and alternative environments like GNOME3 and Mate-Cinnamon without getting sluggish.
Besides that, 1080p video and some light 3D gaming. Again nothing crazy, I'm not a designer and I wont be using stuff like Blender.
One thing I want to make clear is that I want a GPU that is 100% compatible, that means no bugs, no glitches, not having to toggle between propietary and Xorg because it decided to crapout on me.
Thanks for your help
