I have already placed an order for a 675mx but I am having second thoughts. I know some people say to max the system to get the best expected life out of the machine but £2000 is the limit and the 180mx exceeds that. If I was to spend more it would have to be worth it. I am going to be using the machine for advanced 3D applications, photoshop, autocad, 3Dsmax etc. I want to know if I am not going to be gaming (exept for the new sim city) is the 680mx going to be worth it? Curently the gfx is just used to refresh the render preview window but there is speak of further integration with cuda. Any video specialists see any real world benifits in final cut for instance as an example?
