Oblivion supports a FX 5200, but that doesn't mean it play it well at all. He should upgrade if he wants to play BF2, a FX 5700 is the lowest supported Nvidia video card by BF2. It might get enough fps in the lowest settings to be playable; but I think an upgrade is in order. If he really wants to spend 50 dollars on a game that he will have to play on the lowest settings, instead of putting that money to a 6600GT, then by all means let him; but if he thinks his card isn't outdated then he is definatly set for a dissapointment.
