I have had my nVidia FX 5200 graphics card for a while now and am able to play most games very well. I play Call of Duty and Warcraft III. I am now wanting to play newer games like World of Warcraft, Everquest 2 and Doom 3. I am wondering if upgrading my card to an FX 5700 will make a difference. ( i can only afford cards in this price range right now). If its not worth upgrading will my current card perform well with these games? I am running an Athlon XP 3000+
