adding a graphics card.

But your CPU might bottleneck the GTX 460. Also, just because the built in ATi in your girlfriend's laptop is rubbish, doesn't mean the whole brand is bad for gaming. It's a bit silly to jugde it from that. If you have overclocked your CPU, then go for the GTX 460. If it's on stock speeds, best get a HD Radeon 5770.
I have Dawn of War II as well, and I can play on max details on a 1920x1080 no problem with my 5770.

her graphics card is better than mine, so explain why I am able to play all of her sims games with a lesser graphics card???? I dont know why but can

You compared a desktop against a laptop, thats one of them, what GPU does she have? Also most sims games tend to be more CPU limited, so that could be another factor.

this thread is destined for fail.

@op.. if you want a PC for gaming I suggest you buy a prebuilt gaming machine - rather than trying to modify that ghetto one - which will end up being a waste of time.
