@SDColorado - I bought the heavier model: Alienware 17 r5, although they offer an i9 and GTX 1080, I opted for the i7 8750H with GTX 1070. Alienware cooling build can handle it. Plenty of power without the thermals and throttling. 32Gb 2666ram and 512 m2 ssd, $2200.00. I've found so far, the only realistic way to run an i9 with GTX 1080 is in a liquid cooled desktop.
The performance/cost doesn't warrant it for my needs....
I'm about to find out how stable Windows 10 is for audio production, seems like their problem is in the constant updates that might kill your plugins. I hate Windows, hahahha, holding my nose and taking the plunge.....
