For $200 the best card is a Sapphire Radeon 6950 2GB
6950 is slower than a 480, even now with better drivers than its release, its still slower.
The 7850 is actually *faster* than a 6950 (going by techpowerup's charts).
I wouldnt buy a 6950 (thats slower and uses more power) than a 7850, unless it was cheaper than the 7850.
The king of the hill at 200$ is just the 7850, its well positioned and priced, good for the consumer.
