I have the previous gen from Lenovo Y510P with a 2gig GTX-755M graphics card, I didn’t buy it in order to play games, simply wanted dedicated graphics for Sketchup, but it has been able to play Splinter Cell Blacklist*, Borderlands 2 and the latest Tomb Raider at 1080p with pretty close to maxed out settings aside from the anti-aliasing.
Now, that’s pretty much what others have said, I am playing last year’s games, had I known I wanted a gaming machine I probably would have looked a lot closer at the SLI option offered in the Y510P.
*The graphics got a bit glitchy when fast-roping down into dark areas, but that doesn’t happen that often.
