Got a 17k score in the Benchmark and expected smooth 60fps across the board, except in cities where most MMOs have trouble displaying high framerate due to many PCs and NPCs which all have unique textures and so forth. I'm mostly at 60fps but do get drops here and there (down to 35-45) which I cannot explain. Tried forcing Maximum Power in NVCLP but that didn't help (otherwise running Adaptive which does not stress the cards as much).

Did some tests with MSI AB and SLI does work but the GPUs are being utilised up to 50% power.

i3570k @ 4.4GHz
GTX680 SLI
12GB RAM
Maximum settings, Vsync enabled
Fullscreen (due to SLI)
