I am wondering if anyone has experience installing Mountain Lion on a Lenovo Y500

The specs:
3rd generation Intel® Core™ i5-3360M
Chipset Intel HM77 Express (I think, hard to find out im not on the pc right now)
8GB DDR3 1600MHz
NVIDIA® GeForce® 650M dedicated graphics

Should I try with iATKOS or Uni/Multibeast?
