That's what the HD5830 is for. I wouldn't get you hopes up on a fermi card in that price range for a while.
See that i what im waiting for. i want the fermi to drop the 5850 back to its regular prices so the 5830 will hit around the 220-230 mark. if it does i will def buy the 5830 if the reviews prove it to be as good as it seems it will be.
