Is this gaming pc good enough?

I just picked up the alienware m14x R2 from amazon and was wondering if this thing is powerful enough to run the big names like Diablo 3 or even battlefield 3? I'm pretty new to pc gaming, and am only a casual player so I wasnt looking for max specs. The screen is only 720p so I know im not going to get the full 1080p experience, and I don't care about playing on ultra settings or anything, I just want to play with a decent setup and hopefully get 25-35 fps. Will this rig do the job?
