Sending mine straight back; I can't believe ASUS would charge so much for this total pile. I loved my G73SW, it was the epitome of great design. The G750JH is so full of bells and whistles, that it's forgotten to be 'good'.
The screen is terrible, vertical lines between pixels make it unusable for photo/video editing. The on-board speakers are...well, I'd rather not try and remember what they sounded like to be honest. The amp on the headphone socket provides intolerable levels of noise - I literally could not watch movies/play games comfortably for that reason alone. The SSD cannot be upgraded/changed - um, excuse me?! The mouse buttons have way too much travel, making clicking a genuine chore. The bundled drivers/software are severely limited options-wise. It doesn't run that quiet; and, judging from comment #2 below, that just gets worse.
Last but not least, the Assassin's Creed 4 branding under the arrow keys. This basically indicates just how seriously ASUS takes it clientele nowadays. I can't believe I landed £1800 on a machine that doesn't do even the simplest things right, and is upstaged in the above regards by a crappy £400 Acer.
I'm getting seriously worried about you, ASUS - your machines used to be perfect; now, it seems you're pushing it just to see how lazy you can be before it hurts you. Welll, I certainly hope it does, sooner than later.
Do not buy this laptop, folks. Wait until ASUS get their s**t together.
