I'm on my 2nd G750JS-NH71. The first one was a nightmare. Fans running constantly, forgetting it had an NVidia chipset, blue screens. I had to send it back. Ordered another one, though, because I wanted the processing speed, the RAM, the 1920x1080 screen, 7200rpm drive, and the Thunderbolt port so I could continue using a rather expensive FireWire sound device -- the 2nd unit, so far, has been great. Quiet, fast, no complaints.
