We already know that two Radeon HD 6850s in CrossFire are fast. However, based on our exploration of micro-stuttering, there's a fair chance that enthusiasts sensitive to this phenomenon might not be satisfied with the way a pair of these cards behave. If you already know this doesn't affect you, then you're in the clear.

Upon its release, AMD's Radeon HD 7950 was overpriced compared to the Radeon HD 7970, and it performed too much like the less-expensive Radeon HD 7870. After a sequence of much-needed price cuts, though, this card is a much more interesting option.
Keep an eye out for the Boost Edition cards, which include a different BIOS with a higher base clock, a boosted operating state, and higher power consumption. Or, if you grab a reference-class 7950, you should have the opportunity to flash a Boost Edition firmware to it yourself.

Two Radeon HD 6870 cards in CrossFire and two GeForce GTX 560 cards in SLI are very powerful, capable combinations. Just keep in mind that, if you plan to employ resolutions above 1920x1080 with anti-aliasing enabled, you should consider boards with more than 1 GB of RAM.
Bear in mind, though, that this isn't a full recommendation, either. The Radeon HD 6870s remain honorable mentions in light of the findings in Micro-Stuttering And GPU Scaling In CrossFire And SLI.
