Oh GOD! Read This Guys
Good enough for the cheapest 6950 available. It does not have the latest OpenGL API, but that doesn't matter in many cases.
This card is not unlockable. If you try to flash a 6970 BIOS to this card, you will brick it. There is no dual bios switch, and since it's not reference, the shaders available are what you get - there are no extras to unlock. It was built to be a 6950, not downgraded from higher bins.
Cons: HIS has gone down in quality lately and their warranty is pretty bad compared to most.
Other Thoughts: Great card if you know what you're getting. Don't expect a 6970 for this price because you will never get one from most non-reference cards, 2GB or not. This model in particular will never be flashable.
So no F****** flash🙁(. But there's still hope. Can i use overdrive Using catalyst? i did it one time. used 85% of fan speed with 840 MHz! i want it just for better gaming. i mean more frames. and faster render in after effects. i am going to double it in 3 month (crossfire).
