It has a GTX 260m graphics card. It is decent but not great. You can easily max out crysis 1 on it. To increase perfomance, obviously, u should have more ram in ur lappy along with that, you gotta overclock it. Use RIVATUNER to overclock and CPU-Z to have a nice look at the temparatures.
Still, check out overclocking for laptop videos on youtube.
Hope it works out, take care ;D
