Phoronix concludes this card doesn't perform too bad considering its $79 price tag.

"AMD has expanded its Radeon HD 6000 series family, with the launch this week of the mid-range Radeon HD 6570 and Radeon HD 6670 graphics cards. We were sent over a Sapphire Radeon HD 6570 in advance, but as it did not arrive until Monday, the results are only now available. Here is the first Linux benchmarks of the AMD Radeon HD 6570 "Turks" graphics processor."
