Intel is the processor of champions my friend. Get the new Sandy bridge i7. Will rape everything AMD can bring to the table currently. And best of all its only $300. Which is fairly cheap for A. an intel processor. and B. for an i7 thats so freaking amazing.
My laptop im running right now is an Alienware M15x. Set me back $1800 but i got a 1920 by 1080p display, whole keyboard can light up and change colors. Great audio system built in. GTX 260m graphics card. 4 gigs of ram running at 1444. intel i7 720 processor. Also some extras included are a great warranty, customer service is amazing (used it twice and they speak ENGLISH!!! Plus all you do is tell them your problem and its gone.) You also get a stealth mode in which everything is clocked down to save on power. Facial recognition. and a great wireless card.
Friend of mine bought a Asus laptop with the same processor, 6 gigs of ram at 1066 speed. And a better graphics card for around $1600. But after only 8 months his left side fan (I think the graphics cards side.) just died for no reason. He can no longer play games currently because it will automatically shut down on him. Plus his facial recognition refuses to work.
So with this experience I would say go for Alienware. You will never look back on it. And the chicks absolutely love em. I can make the outside of the keyboard "bleed" colors towards the center and they freak out! lol.
