Default Shader Model 3.0 question

Howdy, I got a question about the new cards from ATI and Nvidia. Nvidia 6800 ULTRA supports Shader Model 3.0 but ATI X800 series doesnt. What I want to know is, is it something that ATI can suppoert down the line with updated drivers, or is it something that is hardwired into the card?

Second, anyone know WHY ATI opted not to support it? Thanks a lot.

They have to make a new card to do it. (i think). They took them out for increase in performance rather than quality images. Although my 6800 has both

No they can't because it adds 60 million transistors and increase power usage as a results as on the 6800

Pixel Shader 3.0 is why it is better to go with Nvidia than ATI if you need a new card at this point in time. All the X800 is is a supercharged version of the 9800XT, while the GeForce 6800 with PS3.0 is part of a completely different generation of video cards. You will definately need a 6800 if you want to take advantages of DX9c's PS3.0 features.

the X800 series has a completely different GPU than the 9800xt

If it were even close do you think the x800 would DOUBLE the 9800xt's performance?

The X800 series is based off the same archtectiture as 9800, but with double the pipelines
