I had several problems myself with 6870 crossfire, then was never fully remedied and the problems were consistent across several drivers. Its good to see that Toms HW finally had a nice article on crossfire and sli, I think these few paragraphs really sum up my experience, and the experience of others with a similar setup. What does everybody think after reading these words?
"CrossFire With Two Cards
If you're only judging based on average frame rates, two cards seems like a great deal for the price. We've had several readers write in, though, complaining about this micro-stuttering issue, which simply cannot be seen in the context of normal benchmarks.
Even at frame rates above 50 FPS, micro-stuttering rears its ugly head, pronounced enough to significantly detract from the gaming experience. A paradigm shift seems necessary, at least until both AMD and Nvidia are able to prevent or mask the artifact. Right now, if you asked us whether it'd be smart to "go cheap" on an inexpensive card and double-down later with another one, we'd have to suggest against it if you're the sort to be bothered by micro-stuttering. The improvement in performance would be negated by the phenomenon's impact. Currently, it seems like cards less powerful than the Radeon HD 6950 are not well-suited for dual-card CrossFire. Even if the frame rates look decent, the slower the GPU, the more pronounced you'll see micro-stuttering during gameplay.
At the same time, not everyone is equally sensitive to time-skewed frame sequences, and quite a few cheap TFT LCD displays help hide the effect. Even so, AMD has a major undertaking ahead of it in order to really improve the dual-card experience. "
This pretty much reiterates what I have been saying in that crossfire with any card below a 6950 is not going to produce an overall smooth experience, in sli the problems across the board seem to be less pronounced. What are peoples thoughts on this? This makes me feel a lot better about my personal disappointment in the 6870 crossfire pair that I owned
