Looking for a Gaming Laptop; Asus or MSI

So, I am thinking of purchasing a 16" gaming laptop from either Asus or MSI... Toshiba might be an option too. I choose these manufacturers because they have global warranties, and I will likely be buying in the US and shipping to Japan, where the laptop will live out it's hopefully long and fruitful life.

MSI

Asus

These are the laptops on my short list. I've been looking on www.xoticpc.com because it allows me to shave down the price by lowering ram and HD specs, thus allowing me to get the gaming GPU for less.

I think my top choice is the MSI with gtx570m, but I am concerned about the durability, and the keyboard as well. The Asus might be nice, but the gtx560m that it ships with only has a 128bit bus rather than a 192bit bus, and I'm not sure how big of a difference that will make.

I should also add that I am looking to play Skyrim (will be THE game), Batman Arkham City, Rage, and Deus X, as well as older games that should have no problem with on any of these laptops.

Thoughts, suggestions, recommendations, etc., are greatly appreciated.

Thank you.
