Gaming Colossus. The GT75 8RG Titan marks MSI's relaunch of its most powerful and massive 17-inch notebook. The desktop replacement includes a hexa-core CPU, a 120 Hz display and NVIDIA's fastest mobile GPU to fit its high-end billing. We will be putting this gaming newcomer up against the toughest of competitors.

If you do not need an nvidia1080 and need multicore cpu performance you can buy an Asus ROG 702ZC with ryzen 1700 that in Cinebench R15 (is slightly faster that i9 mobile) with 1422 points and it just costs 1200€ today and also is far slimer and lighter.
I have that laptop from Asus, and I can tell it's a beast! It plays anything you throw at it, plus if you use an external free-sync monitor it looks even better!
