The nVidia GeForce 8400m GS is roughly about 3 times faster than the integrated Intel GMA X3100 GPU. Have a look at the benchmark scores at notebookcheck.com ( http://www.notebookcheck.net/Mobile-Graphi...List.844.0.html ). The nVidia GeForce 8400m GS scores 1328 in 3D Mark 06. The Intel GMA X3100 scores 474 in 3D Mark 06. The X3100 supports Direct X 10, but dosen't have any driver support as of yet. Neither cards will really be powerful enough for DX10 anyway. The GMA X3100 is a very good INTEGRATED card, but no integrated card will probably ever beat a DEDICATED card competitor, as the Dedicated card isn't leaching of the main CPU and RAM! Have decided to get the 8400 m GS in my new XPS M1330 over the integrated GPU as I will be playing HL2 and Doom 3. Wouldn't trust Intel again with my graphics after what they did to me and millions of other people with the Intel GMA 900, not supporting Vista's Aero effects. I and many people are still p***ed off at Intel for doing that. Wouldn't trust them again after that. Long live nVidia!!!
