I saw a really good deal at Costco (Canada) today. HP 15.6" 1366x768 HD Brightview LED/i7-760/6GB RAM/ATI 5650/640GB HD/for only $849.99 after rebates. Never saw another laptop like this, even from Acer. So my question is because this laptop has really high specs processor and memory wise, would it be way to strenuous on the basic 6-cell battery? At first I would get like 2 hours out of it, but what about after a few months? A few years? I'm still unsure if it has ATI graphics switching technology yet, but if it does, would that help a lot? Would an Intel HD + i7 + 6GB RAM still eat a lot of the battery? By the way I'm not a heavy gamer. I play games perhaps once a week at most. I use it mostly for work and design. I'm only thinking about getting this because it's a great deal and sort of future-proof. Thanks.
