It's a 6 month old model, but if the price is right. That video card is very low end and I wouldn't expect more than simple computing with it. It's not very powerful at all. A video upgrade is suggested, but you're more than likely need a new more powerful power supply to run it. The stock power supplies are leave very little head room for video card upgrades.
Off the shelf computers ($500-$700 ones) don't make good gaming computers. Their processors are fast, they have lots of ram, and big hard drives, but the always skimp on a video card.
