Its a big problem for gaming too. The lack a voltage control and being able to use the 260gtx would be devastating.
Take the older area51 laptops with 8800gtx 9800gt and 260m's, your stuck using vista on most of them. NVidia never made a driver that works with those system (that I know of) and Dell only made a vista driver for most of them.
Its a likewise problem the ROG, but with the ROG you can get the card to work right in 7 with drivers off NVidia site, but you loose all voltage and power control so the card will just over heat and shut off. The only fix would be to run the fan at full speed. Even then the system could over heat. I had quite a few older gaming laptop and all but a few with a g92 card ran over 100c at full load.
I did load a few games on the laptop to test like SH3 and the system runs so hot under 7 and with newer NVidia drivers I wonder if Satin had one.
Plop vista on it with the Asus drivers and the card can control the voltage and clock speeds and fan.
EDIT:
Anther side note for gaming, the older laptops with G92 core cards tend to have better drivers for vista vs7 and your likely get higher FPS under vista over 7, if you can get win7 drivers to work witch is more then doable if the laptop lacks Optimus tech. Older systems with Optimus were a nightmare.
