I have an Acer myself, but I modified it. It was pretty much on the same scale as that, but I upgraded my GPU to a ATI 4850 1GB instead, and added some DDR3 RAM, runs any game I play like a charm.
That PC looks pretty decent, but if you ask anyone, building your own PC is your best bet. Although that isn't happening in this case, you should think about upgrading this later on, if it's practical.
