Hey guys! Am thinking of getting the base version of the IMac 2012, just wondering if there's a difference if i run windows on Bootcamp or Parallel for playing Dota 2 (Not supported on Mac yet ). Cos i heard that there may be some downgrade of graphics if i run windows on bootcamp compared to parallel. Anyone knows whether the NVIDIA 640M can run dota 2 on high settings with 8GB of RAM? Cheers!
