i play on a lenovo z580, it has 2gb gt635m i5 3230 8gb ram and windows 8. plays world of tanks on max settings at 20-30 fps i have it set on mostly medium settings and i get a mostly stable 60fps. They only bad thing is the heat build up. i have 3 fans blowing air in underneath and one pulling away at the side, its was a cooler master before i bodged it, i also have the battery removed. i bought it on dabs.ie for 614 and im very happy with it.
