Nope. You need to buy a graphics card that can support DX10 or DX11.
A relatively inexpensive card that can allow you to do so is the Radeon HD 6670 which can run on just about any 300w PSU. It generally costs about $60. A better card would be the Radeon HD 7750 which can also run on a 300w PSU. It is more expensive though at $90 (if there's a rebate) - $110. It is basically equal to the Radeon HD 6770 and is a significant upgrade from the Radeon HD 6670.
