I know exactly what you mean. I have been chasing that white FPS whale since I started computer gaming, trying to eke out every single frame I could to get that smooth as silk performance. My current gaming rig is powerful enough that I typically can play any game with all the graphics settings at the highest without any slowdowns. I even keep Vsync turned on, which I would never do in the past in order to get the best performance.
SLI is a technology that allows you to use two or more graphics cards in one computer. Not all cards can do it, and not all motherboards can either. It allows you to do things like use one card to draw one frame, then the other card to draw the next, and back and forth. Generally it means a performance increase, but not always (which the article explains later, and is something I have seen myself playing Skyrim).
SLI can also be used to improve your image quality instead, by using the alternating graphics cards to improve your anti-aliasing. I have been trying that today, and found it it also improves my micro-stutter issue, though does not completely eliminate it. So far with SLI based x64 CSAA and x16 Transparency AA I only sometimes get a 1 point FPS drop, rather than the 4 point drop with only x4 standard AA. That micro-stutter comes every time I get that 1 point drop. But it isn't as frequent as before, or as bad. I know that sounds strange, but the micro-stutter issue is a weird one, it seems to be caused by people whose computers are too powerful to play the game, not too little. The computer renders frames so quickly that it has too much free time between frames.
