Gotta remember how sli works, SLI splits the on screen dutys in half while tri-sli splits it up three times and quad sli well, four times. Thats alot of paralell syncronized processing going on. I'm not an expert but I'd reckon this is where the driver struggles in its dutys.

Honestly, the performance advantages between sli and trisli vary from gen to gen. It all depends on if you're overclocking and how much. For gaming, it depends heavily on the game playin nice with the drivers as well.

Makes me wonder if they should be work on a firmware update vs newer cards and drivers!
