most BF players won't care about graphics. Of course the nice graphic is good for occasional viewing pleasure, e.g. when you are engineer sitting behind blackhawk enjoying the ride.

Get the Creative X-Fi range of sound card for Battlefield - the difference is between life & death.

My X-Fi died 3 months ago and i rely on on-board sound since then. It really SUX - can't tell the enemy UAV is flying on top/left/right of you. With X-Fi you can pin-point accurately the UAV position and enemies by their footsteps. Got the X-Fi Titanium HD since 2 weeks ago and now can say good-bye to the sucky on-board.

It may not be big difference or any difference if you are listening to music or watch movies but it really makes big difference in games BFBC2.
