Ouch, yeah that is bad. The GT 210 is an incredibly weak graphics card and is not meant for gaming, some of the most recent integrated graphics solutions are actually better than that card. I definitely see why you want to return it, you won't get anything approaching good gaming performance with that card. If you've only had the card for a week, most retailers will probably let you return it.
If you want recommendations for a better card we need to know a lot more about your system. CPU, Power Supply (Brand and Model number, not just wattage) whether you have a regular, or slimline case, which games you intend to play, and what screen resolution you are using.
