How good is the Inspiron 15?

I’m looking into getting a new laptop and Dell has a deal for some laptops on their website. This includes the Dell Inspiron 15. It’s shown here: http://www.dell.com/us/en/home/laptops_great_deals/fs.aspx?refid=laptops_great_deals&s=dhs&cs=19, as the second computer from the left. I don’t know much about computers, I just need something that will run Office and maybe some games later on like team fortress 2. Have you had any experience with this computer?
