Looking for a good gaming laptop but also for work/school?

I'm looking too buy an intermediate gaming computer that i can also use for school and work. My budget is around $1200, but of course less is always a plus. Right now i'm looking at the below links it would be best i know for a 17 inch screen but the computers i see will just break the bank. I'm not that computer savvy but have a general idea. Thanks so much for your input.
