Hi I think it's most important to choose nice processor and graphic card first.
I7-4870HQ and GTX980M... Actually GTX980M is best graphic for laptops than any before.
16GB DDR3 is enough. Other things are less important because you can add bigger SSD later, you can even buy without SSD if you can't afford now.
But CPU and graphics are most important, don't go on 970M.
I'm sorry because I didn't saw earlier to help you.
Off course don't forget ROG rucksack or Shuttle Backpack.
