AMD laptops just aren't up there. And AMD isn't quite up there with desktop processors right at the moment. They'll be back, I'm sure.
I'm assuming that you weren't holding any hopes of being able to lift this laptop by yourself? Or use it on the go?
It'll weigh a ton, and have a battery life of about 5 minutes. And probaly deep fry your thighs if you have it on your lap.
It sounds AWESOME
Though I'd go for Intel, with dual 7900 GTXs
Or you could go for the Quad SLi notebook that's available from somewhere.
