sony grt with nvidia fx go 5600

is there a reason we havent been seeing reviews of the new graphics cards in notebooks. ther r a host of them with the new cards, sony, toshiba, hp. is it because they r crappy and the companies r withholding the reviews. there have been one or 2 reviews which were sort of unclear. ive been wanting to buy a laptop with the new cards for many months. i was about to buy the new sony with the fx 5600. but i saw it at the sony store and played a game that was preloaded (civilization or age of empires 2 i think). it played pretty bad. framerate was bad, visuals were blocky. almost like an integrated graphics solution on a desktop. i mean how in the hell will it play unreal etc. does anybody here own a laptop with the new cards. i think ati 9600 with 128 mb will be the best available.
