If we are talking AGP cards the higher end cards Radeon supported currently up to the ATI FireGL X3 are OpenGL 2.0 . Everything in the higher series are OpenGl 3.3 .
An observation under Linux Powerpc was that the game Torcs would not render properly with a OpenGl 2.1 video card but would with an OpenGl 3.3 card
