I used this laptop around 6 months and it had never lagged any of that time.Nice built quality with glossy look.Hence, it is not a lappy for ultra gamers but can be used by moderate level gamers.
I tried Farcry 2 running smoothly at 64fps and farcry3 is somewhat laggy around 32 fps but its managable.
Low budget gamers can try this but to play trending new games as COD: ADVANCED WARFARE2 or Crysis 3, I wouldnt recommend this.
