“This 55nm AMD chipset supports all of the same
features as the earlier 780G plus more. Among these features are
ATI Hybrid Graphics, PowerPlay, side-port memory, CrossFireX, and
OverDrive. AMD 790GX motherboards can choose to support CrossFire
through dual PCI Express x16 slots but with only PCI-E x8 bandwidth
per slot. While not related to the graphics front, 790GX
motherboards are also able to utilize AMD’s newer SB780
Southbridge, which is a modest upgrade from the
SB700.”
