I recently installed windows 7 on my y500 (by buying a 2nd hdd because i don't wanna void my warrenty...) but i wonder if SLI is working on windows 7, i'm planning to buy a SLI bay for my gt750m if lenovo release those puppy's i saw on couple of forums that they cancel the release for it can some one fill me in please yes, im a noob with laptops always build up my own desktop pc's laptop's are something new for me!

does this work on the GT750m Version of the y500 serie line?
