When you're dealing with integrated (or notebook) GPUs they were really not designed to play new videogames and are mostly there to handle the user-interface of applications and improve video-playback. In other words, I would doubt that either of those cards would be able to play many new(ish) games. With the exception of Alienware (or similar) notebooks that cost $2000+, there are very few notebooks on the market that can perform as well as a 2 year old PC.
