GeForce 9800GTX is not a Power-hungry monster

if they use the same shaders as with the 9600GT it will be a good card

Exactly what my point has been.

The 9600GT is a new rev of the G92 core with fewer shaders, and some optimizations. It performs extremely close to the 8800GT even though the clocks and number of shaders would suggest otherwise.

The 9800GTX will use a new rev of the G92 core, the G92-420.

Since the G94 core supports newer openGL version than the original G92 core, and the new G92 core now supports the newer openGL standards, it is pretty safe to say the new G92 rev also received these shader optimizations.
