I have 2 of these cards and they have been under water all but the first couple weeks I had them.
Cards have 2 gig ram, are in perfect working order. They can be unlocked to 6970's but I have never done it.
Here is a link to newegg for more specs LINK
I only have one of the fans. So one card will need to be under water. I can re-install the fan I have for one of them. Willing to include universal blocks and bridges in a package deal.
The water blocks are the EK black...
