New card works 02/25/2012
You can crossfire this card with another 6870 or another 6870x2 and have very high frame rates with little to no microstuttering as long as the game or application supports crossfire. The card runs relatively cool for the amount of power it draws and the amount of space it has. Under full load with the fan turned up to 80%, GPU1 is at 58 C and GPU2 is at 71 C. Not bad.
Depending on the game, sometimes it won't work as intended (aka no crossfire support for some games). When there is no crossfire support, it will only use the GPU power of one card, but that's not Powercolor's fault.
It's loud at full speed and somewhat loud at idle. What can you expect though? It's two 6870s on one board. I also received a broken card the first time I ordered it and received a working one when I RMA'd it. See my previous review to see what happened with the first one. It also does not overclock too high on stock voltage. I overclocked each GPU by 15 MHz and had some minor artifacting when running them at full load.
Great for bit coin mining!
Also: If you're having trouble running Skyrim with the newest drivers, it's because you have to select the bioshock profile in the Catalyst drivers. It will then work in crossfire mode.
