What are you guys talking about?? There's no way the 9600 is ever going to score 5,000 in 3dmark2003 - a desktop 9600 pro superOC'ed to over 500MHz core doesn't hit 5,000 so there's zero chance of the mobile version doing it.
Actually a score of around 9500-10,000 in 3dmark2001 is the best you're likely to get out of even a MR9600 Pro. The Inquirer ran a few benches with a 9600 mobility clocked at 350MHz core (which is what the Pro is going to be clocked, plus a little auto OC'ing which will add a little, but not so much) and scored 9600 from a sytem with a mobile P4-m 2.4GHz.
Ultimately the MR9600 suffers from being a 4x1 pipe design just as the dsktop version does, except that because it's a mobile card it can't resort to super-high clock speeds to make up for the architecture. It'll probably be a bit faster than the 4200go in the Dell 8500 for shader intensive games like doom3, but until then, for current games it's no faster.
