PConline has published photos of a Unika motherboard equipped with an AMD 790GX chipset.
Quite similar to the 780G, it enables management of two PCI-E 2.0 x16 ports (cabled in x8) and integrates a Radeon HD 3300. This last component can notably utilize a Local Frame Buffer when the manufacturer decides to include one as is the case here with a 64 MB DDR2-800 Hynix chip.
The first cards should be available starting next month.
