Can i upgrade my video card on my m17x laptop?

I'm looking at getting an alienware M17x laptop with a 260m video card and a q9000 CPU (all i have budgeted right now).



Will it be possible to upgrade my video card myself later if I wish?



Will I be able to swap out my 260M with a directX 11 card?



Thanks.|||probably not. But if you are going to spend that much you could get a desktop twice as powerful.
