Ok, just a COUPLE of points here. One if I had wanted a 4870 I would have asked for it. I didn't, I wanted to find out where to buy a 5870 single or crossfire. Two and more importantly, the M17 R1. isn't compatible with the core i series cpu, that would be the M17X R2.
I appreciate that you're trying to help, but from now on, if you don't know the answer, PLEASE don't post a reply.
I am still looking for a 5870 single or crossfire for my laptop. If you have any REAL leads on it, PLEASE let me know. In case anyone didn't see it in the rest of the post, it is for an Alienware M17x R2.
