In terms of raw power, Asus is your best bet.
Among the two Asus the first one has higher clock speed and better graphic card right ? I saw that the 3317u is a 17w CPU and 3120m is a 35w CPU so would the A45VS consume more power ? If the processor n graphic doesn't make a big diff then I'm going for the K46CM
