I guess this goes to prove that there is a lot of lack of understanding of what the problem actually is. This is not a frame dip over a sustained amount of time (like when moving to a more detailed area that slows the card down), nor is this screen tearing which some of you are describing (where a frame partially renders, or the display cannot keep up with the frame rate). This is simply a clock issue. When syncing multiple clocks there are problems which cause cycles to be missed, or hit early. When they are not hit dead on at a specific rate then things tend to sputter, which is what micro-stuttering is
VSync will not fix this because it limits the average frame rate over time, not the actual time that the frames are released to the monitor for display. A higher frame rate monitor will not fix this (could make it worse in fact) because the problem is getting the frames out of the cards consistently.
Think of it like video. Film is shot at 15/24 FPS, your old TV displayed at 60fps (fields per second) or 30FPS (frames per second), and your new TV is at 30/60/120/240FPS (depending on how many children you sacrificed to Best Buy to buy it). The reason the faster frame rates display video smother is not because they are showing more unique frames (the original footage is still stuck at 24), it is because the frames are changed more consistently. In theory they could come out with a really accurate 24FPS TV and it would look just as good, but because there are so many FPS standards (video, film, and all the digital standards) the higher the frame rate gives your set top player more options to display things smoothly (ie try dividing 24 frames of video into 30 frames of disply, vs 24 frames of video into 240 frames of display... something just has to give on the 30FPS). Same concept, just less complex.
In PCs you have no clock determining the time each frame is displayed, it just goes out when it is finished, and it is up to your monitor to display it at the next refresh cycle. VSync merely limits how many frames are generated per sec. It does not regulate the release of those frames.
