I'm still not convinced it works on the Frozrs tbh.
Having a dilemma here atm as well. My 4870x2 died recently so I'm looking at some proper replacement. When looking at the benches with the recent flagships (6990 and GTX 590) I see that a CF setup of 2 6950s gives almost as much performance as these 2 recent cards but at lower cost. Allthough 2 6950's will already provide more than enough performance I'm also looking at unlocking the cards to a 6970.

Currently I have 2 options in mind.

1.) Get two regular MSI 6950s. These are probably reference cards so the chance to unlock is high. Bad thing about these cards is that the cooler is noisy so I would need to replace the original cooler with a 3rd party cooler. I can buy these cards here for just over €200 each and a good 3rd party cooler for about €40 each. If they unlock properly to a 6970 the decent cooler will not only be quieter but could mean the 6970 settings are easier to hold.

2.) Get two MSI FrozrII 6950s. These cards have a low chance to be unlocked to 6970 but already have decent cooling so no need for 3rd party coolers. There is a chance these cards will overclock a little better. These cards are about €235 so the total cost will be pretty much the same as a regular 6950 with 3rd party cooling. If they would unlock it will save me some work.

Any wise words on this from you guys?
