This laptop is a BEAST! Turning on in under 20 seconds from full off, it'll chew through anything, Battery life is about 5 hours power saving, 1 hour performance (Power4Gear Hybrid settings). It weighs about 11 lbs, nothing but it's official bag seems to fit it's extended chassis. It Busts' through AutoCAD 2015, 1080P Full HD powerpoint presentations (VGA output), SeratoDJ 1.6.3, and many games for those other times when I'm not working or DJ'ing! The onboard sound is decent, but I can't figure out how to use the SPDIF out.
I specifically have the G750JX-QS71-CB, the multi-lingual keyboard is a pain at times, but you get used to it quickly. Thunderbolt functionality is amazing, as well as all-around USB 3.0.
