How would the AMD radeon graphics processor with i7 processor work for gaming?

[colffenstein]

I've been trying to get an alienware m11x computer for a while now and i finally saved up enough to buy one with a good processor.it came in a few weeks ago and it was very badly damaged when i took it out of the box and obviously broken before it was put in the box. i called them that night but they were unavailable due to some updates they were doing to the system. i was finally able to talk to them a few day later and i returned the computer and they would send me another computer that would be exactly the same as the other one. I looked at an email that they sent me to confirm my order i saw that it was an intel core duo processor, and they only give me 2 hours to confirm my order which i was unable to do. i called them to tell them that that was wrong and that i want the computer that i ordered they were not helpful. so i think you can imagine that i am pretty pissed off with dell so i'm thinking about getting my money back and getting a macbook pro which i know is better than PC computers.
i just want to know if the AMD radeon graphics processor with i7 processor good for gaming
