ultra thin and light gaming laptop

Hi everyone
wanna ask which laptop will best for me
it will be use for:
1. Gaming (assassin creed, Crysis etc the high one)
2. Multimedia (picture or video editing w/ photoshop or autoCAD or etc)
3. travelling (it will be really much and using my feet not cars)

And I wonder which one will be best
The MSI GS70-2OD (PRO or Base) (start from 1899$)
Or
MSI GS60 Ghost (start from 1700$ )
(Amazon price range)

MSI GS70-2OD specs: (didn't get real specs for pro edition but if the price just different a bit I'll just take the pro edition with gpu nvidia gtx870)
Core i7 4700HQ,
8GBX2 DDR3,
SSD128GB
HDD 1TB,
Wifi,
nVidia Geforce GTX765M 2GB,
HD Camera,
Bluetooth,
17.3" FHD Anti Glare,
Win 8.1

MSI GS60 Ghost spec's
almost same like GS70 but it using nVidia GTX860
and the screen size around 15,6"
smaller and thinner so it's not burden my shoulder too much and not taking table's parts too much


I already aim for razer blade but I think MSI will be better than razer besides its cheaper, both of it almost has the same thick with the same weight. And also if something bad happen, the razer's service in here is really annoy me, I have to go to other country to service it.


Which one would you reccomend to me?(cheaper thinner and lighter will be better but i must have a great spec since this laptop must be for at least 4-6 years)
If you have other reccomendation it will be great for me
