jeje, I stand corrected, they upped the iGPU to HD3000, Which is not so great for Gaming normally.
For gaming you would want to look at the performance for the games you play. For example: http://www.notebookcheck.net/Intel-HD-Graphics-3000.37948.0.html
If scroll down you will see a large number of games and how well the HD3000 does (didn't see your games listed, if your game depends more on cpu power then the iGPU would not be so important.). Did not see what iGPU was with the AMD system, but you could look up and plug that in to the site I used and do a comparision between the two.
