AMD fanboys and those with a myopic viewpoint are propagating a myth that AMDs survival is necessary to keep Intel/NVidia in check. This myth is at odds with reality.
1. The HPC era is winding down, from a mainstream consumer perspective. Nobody cares about gigabertz, and cores anymore, its not 2005 (coincidentally the year AMD stopped being relevant). Dwindling PC sales, and virtually every market forecast indicates that the desktop PC will be highly irrelevant to the average consumer.
2. The future is mobile. The future is SoC. "IF AMD NOT THERE, WHO WILL STOP INTEL/NVIDIA 111!!". AMD is just the first casualty. NVidia will also go the way of the DoDo. The future is SoC. No one needs to "stop" NVidia. If they don't adapt they will also die.
3. You don't
NEED a GTX 670 to game at
playable framerates on most games.

A small minority of users have the latest and greatest in their machines. Intel HD Graphics 3000 tops out at 4.25%. The only reason GTX 670s/Radeon 7990s sell is because nerds want e-peen, and frames they'll never see....Almost every PC game is optimized to run on cards from two generations ago.
The industry is changing in a big way. The future is SoC. AMD is just the first casualty, and them dying does not mean you are forced to buy NVidia cards for $700....NVidia will also go the way of the Dodo because dGPUs are legacy, and not the future.
4. DX9 is still the standard. Windows 8 only brings DX11.1. Nothing significant.
Basically I'm making the point that you don't need the latest and greatest ***, to play a video game. The bulk of the market spends less than $200 on dGPus.

So...AMD can burn in hell and nobody will notice.
