Oh they are but, im just not used to cf and I read that 1 card is better then cf. But, now that I think of it the cards are bout half a year old and they are running great and havent had issues with them, so I'll just keep them xD
id say if you dont like microstuttering (if you are experiencing it) then swap for the 480, then you wont have microstuttering and overall better playability, regardless of what benchmarks say.
