Not a bad deal, this one, has a more powerful GPU, but has a less powerful CPU (gpu is more important for gaming)
I used to believe that as well - it's not that simple these days.
I've been playing TF2 for a while now and my gaming laptop is a Gateway FX series which did play this game very smoothly indeed, however, with all of the updates this game can now become a slideshow due to limitations with my CPU.
I'm led to believe you need both a reasonable GPU and a multicore CPU for the likes of TF2.
