There will be opinions for all tastes, but it is better to rely on objective data. And honestly, I excuse reading a post from N3D :ugly: and less from 7 years ago, if you want to debate on that topic I think you will get more clear from this branch:

[Consejo] Tarjeta gráfica para CAD, renderización 3D y diseño gráfico - HardLimit

PD: And anyway, one topic has little to do with another, one thing is to compare a 3D graphic with a professional one which is something very debatable and another very different thing is to say that an Intel integrated one is going to give a minimum of performance in any 3D application... objectively they perform very little, there is not much discussion possible, a dedicated graphic in a laptop is something highly recommended in general.
