It's part of Dell's weekend sale. This specific model of Dell Inspiron 17 5000 is at 40% off at the moment, $80 cheaper than 2 weeks ago at $959 delivered.
- Intel Core i7-7500U
- 8GB DDR4 RAM
- 1TB 5400RPM HDD
- AMD Radeon R7 M445 with 4GB
- 17.3" Full HD
- 2.83kg
R7 M445 is "low end" comparable to GT940M on ThinkPad E570. There's not many port options either with only one HDMI 1.4 for external monitor. However it's a good price for a big machine as desktop replacement.
Also note that there's currently a Refurbished at Dell Outlet for $899, but one only.
Pro Tip: Add $100 - $200 for a 250GB - 500GB SSD as the 1TB 5400RPM HDD will frustrate you in waiting for things to happen.
SSD will make a huge difference.
