From looking at your requirements you are easily going to get decent laptop for that money.
CPU wise try and find an i5. It will probably come with Win 8 and a lot of laptops will now have touch screens. Not sure if that will come in your budget. Also I don’t know if you will get 1080p.
I think the best way to do it is spend time reading reviews and finding out what you can get for that money.
But a quick look around and found these for a start.
