Asus N750JV or Lenovo IdeaPad Y510p?

Currently I'm buying a new laptop and I wonder which one is better for gaming?
Thank you.

Added (1). Mostly i'm worried about the graphics
Asus:
NVIDIA GeForce GT 750 (N14P-GT) 4GB + Intel HD Graphics 4600
Lenovo:
2x NVIDIA GeForce GT 755M SLI, GDDR5, 4GB (2+2).

Added (2). This asus is not a touchscreen and has more RAM than Lenovo (Asus 12gb, Lenovo 8gb), the processor is the same and the hard drive Asus has 2x1TB 5400rpm, 2.5, Lenovo SSHDSATA 2 (3 Gbit/s) 1TB + 8GB, 5400rpm. But still if Lenovo really has the better graphics and display I will choose lenovo.

Lenovo is better for gaming as it has twoce the power in gt755 sli, but asus will be better in everyday tasks because it is lighter, thinner, and has a smaller power brick and a touchscreen.

Better off with the lenovo it should have a extra slot for adding a graphic card unless one of the gt 755m is being used in that slot

Asus, my brother has it and it is quite the beast for a laptop. I'm pretty sure it's also better.
