Hum, it's hard to change hardware on laptop mate... When I play 911:FR on my dell laptop (intel graphic card aswell) I can't even seen the unit picture... Intel is great with CPUs, but they tottaly suck with graphics cards..
Well if it's a desktop pc I recomend getting an Nvidea graphic card, never let me down before. If it's out of your budget then an ATI should do the job aswell.
