AMD Crossfire Performance Scaling on RD790+Phenom
 

RD790 chipset will officially be known as AMD 790FX part of the AMD Elite Series. Some boxes and boards shots have appeared online and you can see them here, here and here but the official launch will be in November. So far, the FSB overclockability of the RD790 is ~420MHz with a FX-62 and ~270MHz with a B1 stepping quad-core Phenom. We heard overclockability will improve much with a B2 stepping quad-core Phenom which will be available soon and we will let you know how well it overclocks then.
