I would recommend a gtx 460 or an amd 6790. Both run right around $150. For only 150 you aren't going to get anything near max settings. Also you have to upgrade your psu. The recommended amount is at the very minimum 300w for a low end graphics card. You ideally need a mid-high end gpu, but you can't get all that much better performance in your price range. You should be looking for a decent 450-550w PSU. Corsair is a good brand.
