I grabbed a Samsung series 7 about 2 months ago with the new i7 3615m and Nvidea 640M gpu. It boots fast and play D3 and sc2 reasonably well. When just doing word processing I get about 5-6 hours depending on screen brightness. The laptop is also very easy to carry around since its not a gigantic brick.
The only drawback is the fact that its a 1600x900 resolution screen.
