There must be bias in all the forums then because I visit TPU and [H]ardForum a lot and the 6950 2GB is consistently brought up when people are considering buying a graphics card within the OP's budget.
The fact of the matter is the 6950 2 GB is a damn good value and it makes the GTX 570 and AMD 6970 look kind of silly to demand a price premium. Even if the card doesn't unlock, the clocks are guaranteed to go upto at least 6970 levels where it would be around 3% slower overall and still cost $250ish.
I understand that and if I was trying to save money I would get the 6950 also. But the OP said he wanted the faster card even if it wasn't worth it to some but people kept piling on after that.
