Keep in mind though, not all games scale with SLI. Some see little to no improvement. Does SLI do anything for GTA IV?
Then there is microstutter, input lag and the multitude of other issues that come along with SLI. Still, I hold my position that its more a PITA than it's worth and will stick with the fastest single cards I can get my hands on.
