Things are really looking up for ATI.
If they can ping out an 4870 that battles with the 280 in everything, I dunno what Nvidia can do. Not a whole lot. There is only so much they can reduce the price of the 280 due to how much it actually costs to make. When the X2 drops NV will be a bit screwed. Expensive card that doesn't beat much.
Still wont stop me buying a 280 from the States and selling it in a month when the X2 comes out (providing it's better).
