I personally like the G70, and dont mind its massive size, but Im a bit sceptical how the Nvidia Gefore 8700 GT SLI will be with the games. Also, will cooling be adequate because of SLI.

Thanking all in advance!!

i would like to suggest u to go ahead with G70 cuz 17.1" WUXGA+ (1920x1440 resolution) TFT LCD HD/1080p Wide Screen will give u true gaming experience.
