Mayhem for superior performance (check out review

Sager for much better battery life (check out review of same product rebranded

Asus Z71v for BOTH! Okay, I'm slightly biased because I ordered one, but I've looked at both of the notebooks you're considering, and I could get all the features of both notebooks for a lower price than either. (okay, the price may be just a little higher than the 3790) How can you beat that?
