Nice, but integrated graphics, even those that work with online games, are going to limit your performance. It has HDMI out which is good if your monitor or TV supports it, but even so I wouldn't expect stellar graphics.
For a few dollars more from the same website you can get a similar PC with a dedicated graphics card. Look at the 500 dollar+ gaming PCs, there are a bunch in the 500 to 600 dollar range that have dedicated graphics cards with 512 mb to 1gb memory that will run games at a much better framerate.
If you really like the PC you picked out, you might be able add a video card to it. I could not tell from the specs if it has a PCI express slot to do so. You will have to do more research, like reading the reviews or checking the manufacturers website.
