Yeah the MSI GE 70 and GE60 along with MSI newer laptop the MSI GS70 and GS60 are great laptops for gaming. Not all games and programs support SLI, so be careful with those. A lot will only use one of the the gpus
Edit:
Thanks for the best solution. a more accurate way is to say is the dual gpus might be compatible with more than i expected. But if you were to encounter a game or program that didn't support SLI, you are faced with a lower performance.
It is my opinion a single high performance card is a smarter choice then a dual gpus.
