How will SLI work with g-sync?

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

How will SLI work with g-sync?

Something that is wondering me since annoucement.

How will G-sync monitor react to multi GPU setups ?

With pair of gpus you have higher varience of frametimes will those have negative effect on what is diplayed or will g-sync be able to further reduce microstuttering ?

I would suspect that microstuttering could definitely be an issue is the frametime variance is high. I think NVidia's been pretty good about this lately though, and G-Sync will make low frametime variance even more important, so I don't suspect too many issues going forward.

I've read somewhere that G-Sync is supposed to "heal" SLI microstuttering? Maybe it was just a rumor

The quote below is from Nvidia's G-Sync FAQ. Sounds like it should work well. I will definitely be testing it out when i get my hands on one.
Q: How does NVIDIA G-SYNC work with SLI?
A: The NVIDA GPU connected to the display manages G-SYNC. SLI GPU setups work seamlessly with G-SYNC displays.
