The HD 6970 is a good card and in single form it's a good setup already. In Crossfire you've got two good cards that create a great setup, and that's because AMD has done such a fantastic job when it comes to Crossfire.
Sure, the HD 6870 in Crossfire is better value and the HD 6850 in Crossfire is even better value, but out of the three setups this is the fastest. If you want the fastest setup this is the one to get when it comes to AMD cards.
You can see no matter what setup you throw at it, there's just unreal performance across the board. Crank up the resolution, it's not a problem for this setup. Crank up the AA detail, again not a problem. There's really just some great performance from this setup and the bottom line is if you want performance, this is a setup you should be looking at.
We were a little tough on the HD 6900 series. Like I said in my initial review, they're good cards with moments of greatness. This is a prime example of that here, except there are not just a few moments of greatness; the performance across the board is just great.
AMD has just done a fantastic job when it comes to Crossfire and there's clearly not going to be any room for improvement for the most part as we really do see gains of almost 100% at the highest resolution. With that said, there are of course some applications where we don't quite see those gains and Mafia II is one that stands out. It's clear, though, there's a lot less work that has to be done with Crossfire today than there was 12 months ago.
