Heya, the Acer is better. It offers an i7 ivybridge processor that can be clocked up to 3.0GHZ compared to the i7 sandybridge in the asus( I believe what all the websites are saying it has) that has a lower clock speed to maintain battery life and heat.
However, I think both notebooks will do the job you are after. The acer even stretching to gaming on low detail most likely. However, it's more expensive than the Asus, so it's up to you! I'm not an expert at computer stuff though!
