It's impossible to see what you are describing, since the display refreshes every 17ms. (Unless you have a 1000Hz+ refresh rate).

I'm aware. I was using simple numbers to make it easier to understand.

Awesome. Just awesome

I've been running GTX 460 SLI since they came out on dual monitor and have never came across anything like the issues mentioned, maybe I'm just lucky.. although they did not work at all for a few weeks until nVidia released the driver actually supporting sli on them... that was a fun wait...

Though I have already decided to go down the "best single GPU watercooled" route when the 7xxx series AMDs come out, the heat and noise of Palit's 2GB cards is just crazy.

Would microstuttering be more obvious on higher refresh rate monitors? such as the 3d ones? as even though I think 3D is a bit of a gimmick I've been considering getting one for the refresh rate.

I've had about two dozen multi-arrays and tested them for my own use (and others). It's never been about maximum or minimum FPS; My paired GTX580's for example never dipped below 90 FPS in some games and yet hitching or stutter was obvious in certain situations within games.

In fact I ran duplicate systems side by side at the same resolution, one setup with dual 580s and one with a single 580 and tested several games. Even though the single card showed lower max and minimum FPS in fraps, it was easily smoother to the eye. Even my kid noticed it.

I went through all the testing in order to justify my $1000 dollars in dual 580's. You'll note that my sig rig now only has one
I don't have any issues with mine...

It seems AMD Tri-Fire or Quad-Fire setups are the best solutions to get maximum performance with minimal (and probably not noticeable at all) microstutter.

It seems AMD trumps Nvidia again. First with the 6990 > 590 and now this.

Come to think of it, I remember having a high-end (for its time) ATI graphics card in my PowerMac G5, and gaming on it was always smoother than any high-end Nvidia graphics card I have ever owned.
