nVidia all the way. More stable fps in games, no overheating, better drivers, games are designed mostly for nVidia... lot of reasons. Little more expensive, but much better.
Fail stormy. Nvidia cards are famous for the overheating... I know that issue as well.
i agree i got one one laptop with a ati mobility 5850 that thang runs betwen 97 and 103 °C flawlessy when it reach 104°C laptop turn off because of Intels cpus T-Junction, i think the card will take even 120°C
btw it becomes really annoying when it roast ur ballls, maybe somday i will try to moad the laptop it just needs a better cooling
