that would be the 280?
then they re jigged a few things and produced the 285 so it was newer tech come Jan this year.
The 280/285 is the same technology/GPU, same processor cores, same memory architecture, same feature set. Just differences in speed, memory speed etc. The GPU is the same.
Are you sure your not a bit of an ATI fanboy, you have a hard time accepting anything I have said.
