They have a chip thats smaller than a g92 and its competing with the chip thats twice its size. To say they did well, is an understatement! They could grab a tonne of market share - anyone with a an intel/amd chipset is definately going to look hard at what they're offering now.
2x this in Xfire vs a GTX280 - interesting comparison.
Amd is going to cause Nvidia a bit of pain finally!
Tease.
