Good budget gaming laptop?

I'm looking for the best bang for my buck gaming laptop to play on when travelling. It won't need the best specs, I just want to be able to run WoW retail and similar games at 60fps 1080p comfortably. I have a desktop rig for newer games.. if I could get something for less than 600 I'd he very happy. Was thinking the lenova IdeaPad maybe? Thanks in advance
