Bei 2x 5870 und 2x 6970 ging es dann ganz gut.

SLI smoothness vs. CrossFireX smoothness
We don't know what other descriptive word to use, other than "smoothness" to describe the difference we feel between SLI and CrossFireX when we play games. We've expressed this difference in gameplay feeling between SLI and CrossFireX in the past, in other evaluations, and we have to bring it up again because it was very apparent during our testing of 680 SLI versus 7970 CFX.
We can't communicate to you "smoothness" in raw framerates and graphs. Smoothness, frame transition, and game responsiveness is the experience that is provided to you as you play. Perhaps it has more to do with "frametime" than it does with "framerate." To us it seems like SLI is "more playable" at lower framerates than CrossFireX is. For example, where we might find a game playable at 40 FPS average with SLI, when we test CrossFireX we find that 40 FPS doesn't feel as smooth and we have to target a higher average framerate, maybe 50 FPS, maybe 60 FPS for CrossFireX to feel like NVIDIA's SLI framerate of 40 FPS. Only real-world hands on gameplay can show you this, although we can communicate it in words to you. Even though this is a very subjective realm of reviewing GPUs, it is one we surely need to discuss with you.
The result of SLI feeling smoother than CrossFireX is that in real-world gameplay, we can get away with a bit lower FPS with SLI, whereas with CFX we have to aim a little higher for it to feel smooth. We do know that SLI performs some kind of driver algorithm to help smooth SLI framerates, and this could be why it feels so much better. Whatever the reason, to us, SLI feels smoother than CrossFireX.
Things begin with the game engine, which has its own internal timing and tracks a host of variables, from its internal physics simulation to graphics and user input. When a frame is ready for rendering, the graphics engine hands it off to the DirectX API. According to Petersen, it's at this point that Fraps records a timestamp for each frame.
(...)
Now, take note of the implications here. Because the metering delay is presumably inserted between T_render and T_display, Fraps would miss it entirely. That means all of our SLI data on the preceding pages might not track with how frames are presented to the user. Rather than perceive an alternating series of long and short frame times, the user would see a more even flow of frames at an average latency between the two.
