TweakTown posted a review on the AMD Radeon HD 6970 2GB Video Card in Crossfire
Our second HD 6970 arrived and it was from no one other than AMD themselves. We knew that there was only one thing to do, though, and that was to Crossfire this bad boy. In October we saw the HD 6800s launch and when we tested them in Crossfire we were amazed at the awesome scaling the series was offering.AMD Radeon HD 6970 2GB Video Card in Crossfire
While we probably should've done the HD 6950 first, the bottom line was that I was just too excited to see what the HD 6970 could do, so I threw that to the top of the pile. I had my fingers crossed that the scaling we saw in the HD 6800 series was also going to show with the HD 6900s series. There was only one way to find out, though, and that was to test them.
