What resolution do you play your games at?
The problem with uber graphics system is that's it isn't practical for real world PC gaming. Meaning if game publisher tailored every new release for the latest bleeding edge card out there they wouldn't sell as many games because that would exclude 99% of the systems. That's the mistake Crysis made when Crytek released a game that only maybe 5-10% of systems could actually play at a decent frame rate. What am I getting at by saying this? What that means is most games out today run perfectly fine with a decent one card solution. The only reason to need an extra 5-10% boost is if you running at resolutions that are greater than 1600x1200 and to achieve a minimum frame rate of 60 or greater. FYI:Even most console games are optimized for a minimum FPS of 60 if you want to compare. Even if you're running at 120 fps CF or SLI over 80 fps with a single card solution your eye won't be able to tell the difference. (That's overkill)

So what is the answer to how many frames per second should we be looking for? Anything over 60 fps is adequate, 72 fps is maximal (anything over that would be overkill). Framerates cannot drop though from that 72 fps, or we will start to see a degradation in the smoothness of the game.
