For each card, there is only one open-source driver which will work |

with its GPU (r300, r600 etc.). |

Your only modern alternative is to use the official ATI drivers, but |
| 14 |
it's difficult to maintain a current perspective on how they compare. |

At least historically, fglrx has been better for 3D support, but |
| 17 |
radeon has been more inclusive, supporting many older cards. radeon |
| 18 |
has 3D support now, so that's a moot point. Feel free to try both and |

post the results of the phoronix test suite for benchmarking. |
