Early pictures of the AMD RD790 board
 

With the acquisition of ATi earlier this year, AMD is back to making chipsets for its processors. As we all know, the next generation of processors would require HT3 for more bandwidth. CrossFire support should also scale up.

The AMD RD790 chipset is an improvement over the RD580 or 580X chipset. The major difference is that it supports AM2+ and HT3.0
