I just find it funny how Nvidia can lose THAT MUCH performance when MSAA is turned up, when AMD's loss FXAA to MSAA seems very reasonable, I wouldn't say when using FXAA that AMD's frames are low, I'd say Nvidia's frames are high.
Could it be that during the benchmark FXAA simply wasn't working on the green cards thus inflating their score? surely the reviewers would have flagged that though...
