Does the 4890 support pixal shader 3.0?

Ya i shaw the shader, but didnt know if it was the same thing.
The reason i asked is ive just tryed playing nfs shift and it wont play. As soon as you get into the bmw at the start it say windows has a problem. its got 4g of 1066mhz. and it say on there web page the card X1800 has shader modal 3.0. Any idears. . so could it be the card.
her spec it amd 6400 x2 cpu x1800 gpu 4g 1066mhz corsair. msi mobo

If your card runs on any other shader model 3.0 or higher games, then it is definitely either a bad install of nfs [very very unlikely] or perhaps some sort of conflict with windows. If you have windows 7, that could be why I've had a few random game issues but few.
finally update your gpu drivers to cat 9.11 if you haven't already, good luck.

ya sorry thought i was adding on to a diffrent convo. but i think its just the ati cards with shift. there loads of people having problems with ati cards and that game.
