I'll throw a reply in here to my own question... After <mumble,mumble, a whole lot of> hours of rummaging and reading information, I THINK I've got 3, 17 inch boxes that would work:
ASUS ROG GL752VW-DH74 i7-6700HQ, 16GB 2133 DDR4, 1TB 7200 HDD, 128GB M.2 SSD, GTX960M 4GB - $1250
MSI GE72 Apache Pro-003 i7-6700HQ, 16GB 2133 DDR4, 1TB 7200 HDD, 256GB M.2 SSD, GTX960M 2GB - $1300
Alenware 17+ i7-6700HQ, 16GB 2133 DDR4, 1TB 7200 HDD, 256GB PCIe SSD, GTX970M 3GB - $1724 (there are discounts on the 17+), and a 10% discount on all boxes - so final number SHOULD be around $1550
Question: For Lightroom and Photoshop and Helicon and such, is the Alienware box worth 20+% MORE than the ASUS ROG or MSI boxes? Any other 17 inch boxes that would provide equivalent specs and prices? I removed the Acer Predator 'cause it only has a 128GB SSD and runs $1500.
Never mind. Evaluated several machines and selected one.
Which one? I've had a similar ASUS ROG for a couple of years and like it.
