Asus decided to show this marchitecture to Japanese customers in the dawn of its availability and it demonstrated machine and showed a 3Dmark05 score. With two 6600GT cards it scored 5481 marks. Not bad for two mainstream cards.
The same shop is demonstrating the Gigabyte GA-K8NXP-SLI motherboard. It demonstrated Medal of Honor: The Pacific Assault game and it said that the board should be available next week.
No one knows the price of these motherboards [yes we do, Fudo. About $155 for users. Ed.], but Nvidia said that in the US these should cost less than $200. In Japan things always end up more expensive but at least they got them first.
If your Japanese is not good you can find a Google English version here. µ
