I just got my new Toshiba laptop with the GeForce2 Go in it so I decided to load up 3Dmark 2001 to see what it could do. With 128mb of ram and a P3 850 it got 1189 3DMarks on the default test. Not bad considering my P3 866 with a GeForce DDR w/32mb of memory and 512mb of ram gets 2400 or so. I am pleased.
Also the "subwoofer" (lol) actually is noticable and makes listening to the sound much more enjoyable.
