Does HDR remove the need for grad filters ?

As per title, does HDR ( multiple shots taken at different exposures and combined in in photoshop with a graduated mask ) remove the need for graduated filters ?

I should have been more clear. What I mean by HDR is taking two exposures, exposing one for the sky and one for the landscape and then using a horizontal graduated mask in Photoshop to blend the two together. Effectively using software as the graduated filter to split the exposure of land and sky. You might even say this gets a better result as there is no extra glass.

Not HDR tone mapping to make some horrible gauche image.

Background to the question is that I am upgrading my filters to Cokin Z pro, a set of grad ND's is expensive and I am not sure I can really justify them...my other line of thought is that if I only going to get a few filters ( ND and UV and polarised ) I should just get all out and get the Lee filters.
