Well, Dell has gotten to my last nerve. I have explained to them the situation, providing NVIDIA documentation, as well as several others, as to why the 8700M is inferior to the 7950, and I keep being told that there's nothing they can do for me, or I'm being told I'm wrong. One guy told me that I have no idea what I'm talking about. Others say that there is no 8800M GTX, while another said that they can't put the 7950 in the M1730 (d'uh!?) and because of that, I get what I get.
So, I just e-mailed several of the people on that Consumerist link that was given earlier in this thread, explaining things in great detail, and requesting an entirely different system, with the same specifications as the one I am supposed to be getting, except for with the 8800M GTX.
This has NOT made me happy. Being told I'm a liar, I'm (essentially) an idiot, and then telling me that they don't want to do anything for me, because I am "getting what I am getting" (an exact quote from the last rep I talked to on Dell Chat).
