HexiumVII- ATI's (or maybe now it'll be AMD's) RD690 (aka RS690) chipset for AM2 should be able to run Vista well, it'll have an X700 core (but maybe not X700 performance), so running Vista with all the goodies turned on shouldn't be problem.
It'll have HDMI too, so, there should be no concerns with it not supporting full HD.
I'm running a now unstable Super-7 system, and am literally checking like twice a day to find out when the first motherboards with this chipset will be available....it cannot happen soon enough for me...
