Any way there is number of laptops out there with relative good battery life and weight 2.8-2.9 kg using i7-720/740QM. I hope SB mobiles won't be more power hungry.
what i built is for ~500W (150-200W cpu, 250-300W gpu, and 50W for the rest) though currently under maximum possible load its only around 350W

and about the i7-740QM, thats exactly whats in my laptop, and it gets no more than 2.5 hours of battery life IN IDLE. its really crappy, and thats with minimum brightness and power saver mode. its a dell e6510 with a 6 cell battery.
