The new Alienware 15 R3 and 17 R4 laptops are on special for the first time since release (released in September). The discounts are pretty good, roughly 20% off. FWIW, if you order via their online chat you might be able to get another 1% off (I was), but the person I spoke to was adamant they couldn't do better due to the existing discount.
These are the new versions with Pascal graphics (GTX 1060 / 1070 / 1080). These graphics chips perform within 10% of the desktop equivalents, so you can actually get 1080 performance in a 17" laptop, or 1070 performance in a 15.6" (albeit a very large 15.6").
FYI: there was a problem with these laptops overheating, however it was found to be an issue with the thermal pads being too large causing the heatsink not to be mounted properly. They have since rectified the problem. You can find long threads about the laptops and problems / fixes on Notebook Review forums:

Looking at the 15 R3
$2,149.00 = 2063 if Cashback applies.
The prices are pretty ordinary when you compare it to Kong computer's Black Friday deal for a high end, i7HQ + GSync + GTX 1060 + 16GB RAM + 512GB SSD laptop with no OS built in ($1879 + $100 for Windoze = $1979)

On a bargain-o-meter scale, I'm giving this a
3/106/10. Alright deal I suppose if you want a Dell, but the Kong laptop has better features.
