"This means the birth of $199 to $249 DirectX 10 part is not that far away after all."
Yuck. It reminds me of when the 6600GT came out at $200 and the price stuck there for a year. The most expensive card that I ever purchased was the 7900GS for $130 in my system right now.
Decent performance in most games ought not cost $200+ . No DX10 for me for a while.
All those DX10 cards in the near future with very little actually running on DX10. (sigh) It would be no surprise to learn that even a mid-range DX10 compliant card will require a 400 watt min PSU.
