how's sager np8760 cpu/gpu temperature?

i saved up around $1800 and was thinking about buying new laptop. i want one with 480m equipped but it seems it's too expensive. so i went xoticpc.com and saw sager np8760 which is equipped with 5870. it seems price is in my budget but i am worrying about gpu temperature. i hear how hot 5870 runs everywhere across the asus g73jh model which seems similar to np8760 and was wondering what's idle and max temperature everyone get on np8760 and would like to know battery life as well. if there's proper review of this laptop, link me plz.

one more thing. i hear 460m or 470m equipped laptops are coming out pretty soon. when will they come out exactly and what will their prices be? i kinda feel like stick with nvidia if possible. i hear 460m perform worse than 5870 but as long as it runs cooler and runs almost up to 5870 with similar or lower price, i wouldn't mind having one.
