Today, there will be many releases of the Radeon 3870 X2 dual chip card, and AMD, PowerColor, Club3D, Gecube, Sapphire, MSI, Asus and many others will be ready to showcase it at the Distree XXL show in Barcelona.
Many will overclock the cards, and we've heard that some companies might even try to push to more than 850MHz. Some of ATI's partners will have a custom dual fan cooler that should be more efficient than ATI's own, but this completely depends on the AIBs.
The card should retail at about €409 to €430, and there should not be shortages, as partners got enough of the cards; but we have heard this before.
We can confirm that Radeon 3870 X2 is, on average, 50 to 70 percent faster in games with AA, compared to a single 3870; as a single RV670 is simply not powerful enough.
