I pre-ordered the 8th edition of the Red Book and will be learning OpenGL 4.3 from it soon. However, I read on Wikipedia that the supported video cards for OpenGL 4.3 is GeForce 400 series at the minimum. Does this mean that I will need one of the supported video cards to do simple tasks in OpenGL 4.3 such as drawing a cube, or will I only be restricted to certain features without one of the supported cards? If so what features?
