1) wich games? for et its ok but something like battlefield3/4 or cod bo2 its a shit grapiccard, even on et when much players are on server.
2) i have a 500€ Grapiccard on my pc and the same shit as you have on my laptop and i see no difference at the movies...
3) the ram on the grapic card is not the most important 1 gb is mostly enough. the gpu on the grapic card should have much power.
