They look good. my only concern is where they say discrete graphics. Which leads me to believe that your graphics memory comes from system memory. My point is that if its what I think it is that means the graphics processor may be built into the board and if it fails is not replaceable.
That is why I went with a video card laptop. Companies like Sager, OCZ, Alienware/Dell-XPS, etc make those sort of systems. In my case if the video card fails its possible for me to get a card to replace it. It had alot to with my choice. I bring this up because of the price I saw for the one you linked too. 1899.99 for that price you could get a laptop with either SLI or Crossfire.
What is nice is that if you go out there you can have one of those companies customer build your system to the way you want it. Its how I did mine. Mine is Ati 3870s in Crossfire and upgraded the memory after I got it to 4gigs. While mine is only a 2.24GHZ the CPU can be upgraded to a quad core. You can save yourself alot of dough if you willing to do some of the upgrades yourself.
But I will say the spec on the one your looking at looks like it could get the job done. What might also help you in your choice is going to http://forum.notebookreview.com/ and go check out what they have to say about the laptop your looking at. This site had been a great help to my making a choice. Hopefully it will for you.
