well while Iwas surf'n around I came across this article @ Hot Hardware
http://www.hothardware.com/viewarticle.aspxIt's about the sickest Mobile Graphics accelerator you could think about if' it's all about pure speed
Nvidia's GeForce Go 7950GTX
here some sweet specs of it

But yes it's something nice from the Green camp, though it still lacks Combined FSAA & HDR support, so waiting for a G80 is very worthwhile it, but if FSAA ain't such of importance and HDR with pure speed is it's the best to get for the Laptop Gamers market
otherwise there is ATi's M56 Mobillity Radeon X1800XT
