The 880GTX is marked for launch mid-end of July, which isn't that far away.....I wouldn't call these "rumors" at all......a leak 45 days from launch has happened before, and does happen frequently, with accurate information/specs....remember the 680GTX rumors?? which turned out to be correct.
Do you guys find the leaked specs to be out of this world or something, cause their not to me, their right on par with what was expected....
Until the day of launch, EVERYTHING is a rumor. Even the launch day.
