There are two types of 6950 unlocks:
Type 1 unlock: Shader increase to 1536 units (same as the 6970)
Type 2 unlock: Complete BIOS flash to a 6970
The type 1 unlock is almost risk free and can be achieved with almost all the 6950Â´s.
The type 2 unlock on the other hand is a bit more risky because due to the full 6970 BIOS flash also the timings of the 6970 and other settings which are different will be applied.
To some cards that ultimately can lead to card failure or mailfunction.
Further marginal differences can be seen here:
But be advised that the Type 2 unlock only yields about 1-3% performance increase.
Wheter the Type 1 unlock + stock 6970 clocks have shown to yield the exact same amount of performance a normal 6970 would achieve
So according to those results one could imply that a Type 1 unlock + stock 6970 settings would upgrade a 6950 to a full 6970 performancewise even though other settings or structural differences are unequal.
Both types of unlocks will void your warranty if something goes wrong so be sure to bare that in mind when doing it.
There have not been any long term studies about the affect of the unlocking process and further causations yet.....but I am confident to say that nobody has encountered any problems yet
So I personally would advise you to leave the unlock be as it is not included in the warranty and just overclock your card 5-10% higher ...thus a higher overclock should be able to not only compensate but even exceed the performance boost the unlock provides
And if you must have an unlocked card at least wait until we know more about its long term affects
I would also like to refer you to my thread in which similar questions and all advantages/features of the 6950 including all designs etc etc should be displayed and answered
Seeing that you have already read the techpowerup review there shouldnÂ´t be many questions left after reading this
