It all has to do with the Canadian site, I configured what you did on the U.S. site and was pretty pissed... Had a not-so-nicely worded discussion with a sales rep supervisor on the phone about it. The HD 5850 version in the M15X is the GDDR3 version and not the GDDR5 version so the GTX 260M is basically just as good, plus I'm an Nvidia drivers > ATI drivers fanboy. That and CUDA is great shit.
