The asus is over priced or under speced. The sager NP9170 would be a good choice with the gtx675. It is the msi gt70 chassis if I remeber correctly. Its 1300 its a much better deal then the asus. and it will blow both out of the water. the asus you listed isn't any better for gaming then the lenovo. It says $1399 but it is $100 at checkout.
