The gang at HardOCP have written up a bit on the ATI Mobility Radeon X700 core using an Acer Travelmate notebook. 
For the class of notebook that this is the Mobility Radeon X700 is at the top of its game. It allows the highest level of playable quality settings we have seen yet for this class of notebook. Though the gaming experience isn’t going to be as great as a desktop replacement laptop you can still have a whole lot of fun on the go gaming with this notebook.
