Dual-Chip Radeon X1600 XT Graphics Card to Cost $399 – GeCube.
......
The chip works at 590MHz and is equipped with 1380MHz 128-bit memory. Theoretically, the product can demonstrate performance similar to the Radeon X1800 XT, but in reality multi-GPU technologies, such as Nvidia Scalable Link Interface (SLI) or ATI CrossFire, cannot boast with maximum efficiency.Moreover, recommended pricing of the Radeon X1600 XT is $179, which means that users demanding a multi-GPU computer based on two of such chips can get two Radeon X1600 XT GPUs at a lower cost than $399.
