Over all this was a good review. Regarding heat dissipation, it does get HOT when gaming and in my opinion the keyboard and the palm rests will eventually become uncomfortably hot.
Other issues with this machine:
The fancy customizable colors on the keys worked well for the first 6 months but since then there's been a steady degradation in the reactions. Most of the keys still display the colors and behaviours that I programmed in but some of them seems to have LED failures since the colors should be red until pressed and then light blue upon being pressed which then fades back to red. Instead the colors on some keys (an increasing number of them) are now turning dark blue or purple and then when they fade back it looks clunky.
Also, for as loud as then fans are in this thing it sure doesn't move a lot of air. you might think about getting a cooling device to set it on top of.
The keyboard: only a year old with moderate gaming (1 to 2 hours a day at most and not every day) and light work use, and I have the left shift, the "A" and the "S" keys have rubbed off.
The air ports on the sides have thin plastic structural pieces that will break off quite easily. I broke mine by putting the laptop in my backpack when there was a usb drive down at the bottom. as soon as the full weight of the laptop rested on the usb drive it snapped those little tabs.
So my review would be "Great performance, gets hot, hardly ever freezes up, fast enough for new games, but the keyboard isn't as awesome as you would think."
Plus the usual things you get with Windows such as PC waking up randomly for no reason, Adobe acrobat updater persistence to the point of anger, foggy HDMI responses (plug it in and it doesn't catch the sound portion of the signal, unplug and plug it in again and maybe it does start outputting sound or maybe it doesn't), other audio issues possibly from having three different companies and their software, PLUS the OS in control of the same audio HW. Good luck figuring out what happened to your microphone.
