The 3dmark05 score is too low. The alienware 51m 7700 has the exact same specs as a sager 9860 which consistently benches around 2900 stock and anywhere from 3500 to 3900 with performance drivers and overclocked. These speeds are sustainable and run games great - see sager forum. It is also unfair to compare against an x800 which is just a better GPU flatout. Accord to most sources though, the mobile x800 with a high gpu clock will be available for upgrade for the 9860 just as soon as ATI actually makes enough, as will the new intel em64t processors.
I like it. My only complaint is the lowered clock speeds on the graphics card. Eh, it comes with the "mobile" territory. That thing will still eat through games at high settings, though. Oh wells... I'm getting 60 FPS instead of 80.... *cries*
