Depends what you want from the game, and which console you feel most comfortable on. I don't know if you will see much diffence on the PC if you aren't upgrading, but you might get a more 'hardcore' experience. Do you have a headset for the PS3? Squad play is big in this game, so if not maybe go for the xbox. But the xbox does have the HD pack download, so only get that one of you have one with a hard drive.
PC obvs and you card will handle BF3, it just means you won't be able to play at ultra settings - no biggie.
