To me, it seems like both these laptops will provide amazing performances for games and apps alike and the average battery life is roughly the same but that's not much of an issue. I want a laptop that can last me for a long time, I'm talking 2+ years.
The Sager has the SLI 285M GTX Nvidia cards, but my question is, is this option better than the Mobility Radeon 5870 HD that the ASUS g73jh provides?
Hello and welcome to the forums
2 GTX 285M's perform better than 1 5870M.So the Sager model will do better in gaming.
If you need something faster, have a look at AW M17x which has 2 5870Ms(that perform better than 2 GTX 285Ms)
