I'm currently getting into OpenGL, but I've experienced that my graphics card only supports OpenGL 3.0.
So i was looking for a modern graphics card but soon got lost under the large product range on the market.
What I want is a graphics card which supports one of the latest OpenGL versions (4.3. would be perfect) while not being too expensive.
I really don't need a high-end graphics card - just one that supports a halfway new OpenGL version so that I can learn and try the OpenGL features of this versions.
Is there a graphics card on the market which meets my expectations and can you give me some advice please?
I really want to spend as little money as possible as I'm still a student.

Thank you in advance,
