I need a laptop as I am selling my desktop. I am only doing this because I move to places a bit and it is a bit hard to carry a desktop and a 21" screen
you can try looking into an Asus N56 JR. they are a bit over but they have a 4700HQ processor and a 760m video card. its also built well and remains quiet under load without running too hot. I use one myself and its a great machine.
here is a good review, with benchmarks and everything.
this site has really good reviews of many laptops so any models listed in there you can look up for reviews so you know what to expect.
