Excellent machine, very nice keyboard, great screen, this power: Aluminium Black (Intel Core i7, 16GB RAM, 1TB HDD + 256GB SSD, NVIDIA GeForce GTX970M 3 GB, Blue Ray Windows 8.1). the laptop does not sound it is very quiet. unfortunately computer very heavy and very heavy and large changer adapter. So the computer is not comfortable to carry due to the heavy weight.
